You can't use the 'next' button, there are shotguns that shoot singular projectiles, the silencers are useless and in the end this just feels completely unfinished.
I thought I could get some fun out of this so I started it up and it seems like it's one thing after another. First I couldn't recognize all the card stats after playing it ages ago so I tried to start a new game. Spoiler: you literally can't start a new game. Then I try to speed up the game so it's not super slow, but that's not unlocked until I play more with these tedious, slow animations. Then I tried to customize my deck, but in order to sacrifice my cards I need to take them out of my non-optional other decks. In order to even do that, I need to place other cards in. Then, just as a final kick in the teeth, it turns out that I can only play a certain number of times before needing to wait, despite this not solely being a mobile game.
I know you guys wanted to make something fun, but making people wait for every little thing and not giving them basic features like a way to start over is not okay.
