Your menu says more great games, that is gross assumption that this game is great. To the contrary this game is crap. Total crap. Its atari 2600 quality, with annoying music. I dont know how you got selected for the weekly challenge but quiet anonymity is where you will end up with this worthless time sink.
A poorly constructed button masher. Infinite spawn + doors that unlock on kill count + low ammo + ammo per weapon type = 1/5. This is a frustrating game with little reward for playing. It's like an old style side-scroller with no compelling reason to play it. Author please either remove the infinite enemy spawn, or add infinite ammunition please.
