### 4/5 — Please introduce regional pricing for in-app purchases in third world countries

*2026-01-12*

I would buy all 3 packs if the prices were 1/4th since my country has less purchasing power.

### 1/5 — Garbage game

*2026-01-07*

I’ve been playing this game for a year now on my iPhone and two days on my iPad and it doesn’t load my progress it just keeps freezing and saying failed to load data please restart your game on top of that I had to pay for no ads twice which is stupid, if the developer is reading this, you’re really bad at making games that work but great at stealing peoples money.

### 5/5 — I Am Within No Hurry!

*2025-10-29*

Going Steady!

### 1/5 — Энергия в 2025? Вы серьезно??

*2025-05-14*

Тут без комментариев, как только после начального боя увидел в игре систему энергии (что бы поиграть надо потратить энергию), то сразу вышел и удалил игру.

### 4/5 — When will you bring back the formats?

*2025-02-01*

Galaxy Background and The Flaming Eye of The Lord Of The Rings!

### 4/5 — Need more lvls

*2025-01-04*

Good game, just needs more levels.

### 4/5 — On the defence!

*2024-10-28*

Not new gameplay, but an interesting cover

### 3/5 — No option to rebuy purchases

*2024-09-01*

Maybe I’m missing it but I’m not seeing where it lets me re-get ad free. I got a new phone same Apple ID but it’s making me rebuy and start over I have the account connected to my Apple ID so I’m not sure why it’s not giving it back.

**Developer response:** Hi, you can contact us at service@cyberjoygame.com with your game id and your Apple ID as well. We will help to check on it for you. Thanks!

### 3/5 — It’s alright

*2024-07-21*

Fun to grind and get stronger but tournament is locked behind a paywall and game gets boring since devs never make new updates

### 4/5 — Pretty decent game

*2024-06-06*

I like this game, it’s a fun game with a lot of upgrades to play with over a period of weeks/months. But I do have a few criticisms. My biggest being that it often feels like you can’t get enough gold, even after I purchased the 1.5x multiplier and upgraded my gold bonuses in the hub. You often are stuck waiting for enough gold to upgrade and finally pass the level. I’ve been stuck on the boss level andromeda for 2 weeks, and even after purchasing 2 skill upgrades (chapter packs) for $10 each I still can’t quite pass it (but I’m close.) Before I’d use the long challenge levels to grind extra gold, but now I’m stuck pn the low waves of #4 and can’t access the past levels. My damage upgrade is are 150k+ and I get ~20k when I play these two levels I’m stuck on. Going to past levels takes a very long time with a gold yield that’s scaled still too low imo. Trading gems for gold is not worth it, as it’s 80 for only 160k when 400 gems costs $5. So the gem cost is too high to justify doing it. Other than that the game has been good, but I sometimes wish there were more enemies or features that made the gameplay more interesting/interactive once it’s gotten kinda old. More weapons would definitely make it more interesting. I originally came here when “the tower” app stopped working after a day, and it’s a problem many users have had for many months that they refuse to fix. I hope they continue to develop this app and add new features/levels, because it’s a fun game to play for a bit inbetween other more involved games.
