Buttocks ### 3/5 — Collision and control. *2021-07-31, version 1.8* The game is very nice graphics wise , controls pretty much do what they want and the enemy’s bullets zap you even though they’ve missed you by a mile ### 4/5 — Endless Wave *2021-05-24, version 1.8* I never use special weapons, except for maxed out missiles, on the actual levels. You do need certain things in order to do well and you can sit on a lucrative level to attain needed upgrades although it is very tedious...but doable. It’s the endless wave section. Even with all upgrades I can’t get over 20,000 points. Maxed out special weapons and all other Max upgrades won’t do it mainly because the energy regeneration rate, even maxed out, is way too slow to support special weapons effectively. Recon is great because regen rate has a supercharge option and is much faster. So trying to get a high score here is virtually impossible without a faster energy regeneration rate. A supercharge option would solve this, but otherwise it’s really not worth it. ### 4/5 — not bad but upgrades required *2020-06-05, version 1.8* I like this game to be honest it fun and cool but on some levels u need like a specific upgrade that is kinda expensive so u basically can’t beat the level for a while. But overall nice game🙂👍 ### 5/5 — Brilliant game *2020-05-18, version 1.8* Didn't spend any additional money Great way to pass time ### 5/5 — Good game *2020-05-13, version 1.8* Lol ### 4/5 — Good for a flash game... *2020-04-10, version 1.8* But frankly I think you can do better, you draw inspiration from classic Atari games such as space invaders. Not once did you try to pressure me with pop ups in game o give you a 5 star review or buy coins. Which is the kind of thing more developers need to do on the app stores. But let’s move onto flaws, i noticed hit detection can be spotty, almost like your ships hurtbox is larger than you can visibly see. Also it lacks significant story, I did not feel much draw to continue(level 46 and counting btw). Overall in my rating system I this game as A tier. I will keep an eye on you and hope for improvement in the future. ### 4/5 — Brilliant game *2019-12-15, version 1.8* Just love playing it. ### 4/5 — Complaints *2019-12-09, version 1.8* 1. I cannot beat wave 46. 2. 90% of power ups and upgrades are overpriced. 3. I used to play this on another device and the bullet recon reflected enemy bullets but on this device it makes enemy bullets disappear. Poof! Clearly this game needs some improvement with power ups and bullet recon. Thank you ### 5/5 — I love this game it is fun *2019-12-01, version 1.8* Your game is very fun I love it so much it is so cool. I play your game every single day. From Parker Luck. ### 2/5 — Reached level 50 and had to pay to continue. *2019-11-03, version 1.8* I reached level 50 after a few days off for fun. Level 46 & 47 were very difficult but possible like the developers claim. They also claim in the reviews that they’re built it in a way that in app purchases aren’t necessary. Until you reach level 50. I made a few in game purchases to upgrade because it was more fun that way. But I’m unwilling to pay more. Too bad. ### 5/5 — Good game *2019-10-04, version 1.8* This is a cool game. Not money hungry like others. Pretty cool action. Could be a little easier but still awesome game. ### 4/5 — Level 46 *2019-09-12, version 1.8* I love this game but level 46 is impossible and I can never get beyond it ### 5/5 — Best app ( game ) ever *2019-08-21, version 1.8* Beeeeeeesssst gaaaaaammmmme evvvvvvveeer ### 4/5 — Fun *2019-07-30, version 1.8* Really wish I could turn off the bullet recon :/ ### 5/5 — Addictive *2019-07-25, version 1.8* Very fun and challenging ## Most critical reviews (10 lowest-rated) ### 1/5 — needs update *2022-10-03, version 1.8* need ability to move ship with 1 finger instead of lame arrow controller ! ### 1/5 — Not fair *2020-03-05, version 1.8* This game is not fair and set up to get your money ### 1/5 — Too hard to be fu *2019-01-11, version 1.8* No matter how hard you try,you can't progress past a certain point without buying medal...clever ### 1/5 — No no no!!! *2018-12-25, version 1.8* Really not happy. I paid for three lots of coins. Then I get to the end of the first invasion, and I find that I have to pay more for the next invasion. I cannot go back and repeat without losing everything I paid for and all my progress and present winnings. What a BLOODY RIPOFF!! You should be ashamed of yourselves. I wish you lot were in my sights ! Buyers beware. ### 1/5 — Worst game ever *2018-11-09, version 1.8* Ievels are to hard it made me cry ### 1/5 — Pay to win *2018-09-07, version 1.8* It gets to a point where its borderline impossible to pass the level without buying upgrades with real money and you cant even earn the money because the level is so hard it takes you 10 shots just to destroy 1 of 20 ships while getting shot from every direction possible with no chance of dodging ### 1/5 — Uncomfortable movements *2018-07-09, version 1.8* I was used to moving the jet with the point of my fingers for full movement. Here i can move only left and right, very restricting.... there are more developed games in its category. ### 1/5 — Low level and stuck. *2018-05-14, version 1.8* Stuck very early on, so only way out is to buy to get more powerful.... so deleted game. You can’t redo a level, so it’s rubbish, as get stuck early on... ### 1/5 — Poor execution of a scam idea *2017-12-14, version 1.8* Code a circa 1980s Space Invader clone. Add a system of monetization that renders the game from easy-peasy to bloody unplayable in 15 minutes, add $5.00 of in-app purchases to make the game playable again, rinse, repeat. Take Unity engine, add some $10.00 3rd party gfx and not a great deal of cleverness and try to make money off the unwashed masses. EPIC FAIL! Do not buy. Waste of time, on all levels. ### 1/5 — Over the top stupid *2017-09-09, version 1.8* How the hell are you meant to get past 43 it bloody stupid nOt doing anymore they can shuve the cheaty game ## Most praised reviews (10 highest-rated) ### 5/5 — Fun game *2026-03-15, version 1.8* Challenging and fun ### 5/5 — Fantastic free game *2026-03-10, version 1.8* Would recommend highly if you think your good enough 😁 ### 5/5 — Still amazing *2024-04-04, version 1.8* Used to play a decade ago opinion hasnt changed ### 5/5 — It is best *2023-03-25, version 1.8* This game is so fun! So 5 ⭐️ ### 5/5 — Old school *2022-04-01, version 1.8* Love this game. Controls are easy and the game does not seem to be glitchy. I think this game was put together and reminds you of the old school space games ### 5/5 — CK/Avenger *2021-10-10, version 1.8* Love this game only a beginner but, I’m learning ### 5/5 — First 100 waves r so easy to do it *2021-10-09, version 1.8* Used to play on iPhone 6s and bought the additional levels but as soon as I upgraded to 12 pro max , app is asking money again. It supposed to be free when I already bought the level just changed the phone but iCloud I’d is the same. Did it happens to anybody else or it’s just me. I really miss the additional waves but won’t buy it again. ### 5/5 — Space Cadet *2021-08-06, version 1.8* Space Cadet is so good and awesome because it’s very easy , sometimes there are very hard levels but you get through it . Like how Wave 5 was so hard it took me 1 hour to get through the level . It’s so amazing , and you should rent it . You have to try this . It’s so good . ### 5/5 — Great game for kids! *2021-04-03, version 1.8* It takes both my 5 years old to play this but they love it! ### 5/5 — Great retro game *2020-09-10, version 1.8* We all need more games like this. Very fun. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/). User reviews are verbatim App Store reviews.
