The game is a good idea, but I think you need to add objectives, a story, change the control system and/or explain how it works ex: tap to shoot maybe add a joystick for movement for better maneuverability and that would allow for you to manually shoot and move at the same time, add a tutorial I didn’t realize that if you put two fingers on the screen it shot straight until level 40 out of 100 as well as many other things, also please explain all of the enemies, half of them don’t make any sense on what they exactly do. This a great concept for a game, but it’s missing a few key components that could probably make it a top ten game in the App Store. I also really like how you guys aren’t shoving ads down my throat, I understand thats how you make money, and I appreciate you not being super excessive about it. The app does crash from time to time which is a bit of a bummer, but I think with some patchwork and some new ideas as well as more explanation to everything, I think that this could be a 10/10 game. Also, an online multiplayer option would be really cool and fun. That’s my take on it, best wishes to the developer, I think that if you implemented some new ideas, your game would do even better.
