But the AI is unfair to the human gamer. To the point that I find the game unplayable **Developer response:** Thank you for the review. I’m working on a new version. Stay tuned :) ### 1/5 — Game needs some fixes... *2018-01-08, version 2.1* Tank Wars would be proud...if this game were a little more like Tank Wars. These random asteroids come in and wipe you out on practically every other turn. The enemies in the game have access to far more advanced weaponry and at a pace that far outsteps the meager upgrades you get once in a great while, and your attempt at firing at your enemies is “sabotaged” every other turn (sometimes several turns in a row. This game needs some serious tweaks by the developer to make it far more fair to the human player, and needs to be toned back on the sci-fi/espionage theme to make the game a little more like that which it is trying to emulate. Graphics are good, however, and, within reason, it is similar to Tank Wars. Still, I wouldn’t waste my money. ### 5/5 — Awesome *2017-03-24, version 2.1* Tank wars would be proud. ### 4/5 — Like it *2014-09-16, version 1.0.3* I too wish you could go back and play earlier levels but hey ya can't have everything. It's a fun distraction and a good little game. ### 4/5 — Fun game *2014-03-20, version 1.0.3* Enjoy the game and glad the ironvale issue was fixed. But would like the availability to replay levels and would also love to see a multiplayer game type to play against other people. Hope to see it soon!! Thanks ### 1/5 — Not good. *2014-03-05, version 1.0.3* Looks neat but very dull. ### 2/5 — Rubbish *2014-03-03, version 1.0.3* Pretty game but devs forgot to make it fun. ### 5/5 — Good! *2014-02-27, version 1.0.3* I enjoy playing this stylish version of the tank game and it is worth noting that the developer has fixed the Ironvale issue. Still hoping for the ability to replay levels but overall, it's a fun game! ### 2/5 — Stuck at Ironvale level ((BUG)) *2014-02-26, version 1.0.2* My player is off screen and once I shoot I explode. BUG! Please fix. ### 3/5 — Bug Halts Gameplay 3/4 through *2014-02-25, version 1.0.2* In the Ironvale level, you cannot proceed as you are rendered off the screen and explode immediately when it's your turn. This level is 3/4 through the game so you cannot proceed until they fix this bug :( ## Frequently asked questions about YesSir ### What kind of game is YesSir?
