I really enjoyed this! With a bit of polish and balancing, I could see this turning into a pretty cool mobile game, easily. I find it especially interesting how it seems like we both had the same idea, but ended up taking it in completely different directions, seeing as my game is also a one button top-down shooter. I like how there's a tactical aspect to it. You can't just run and gun, you really have to get familiar with the pickups and decide which ones are good for your current situation, and which ones best suit your playstyle. Good job!
