A well made game!
I do have some feedback though, I my experience with the game, I find it annoying not knowing when I can or can't shoot on how much I have left for it. I do like the new abilities that you can buy, but the trading system, seems or at least that is how I saw it, that it didn't do really something else than just opening a chest??
What I also would like to have is that maybe you can call for the partner, so they walk towards your direction, the AI seems to be walking into the enemies, I would maybe like more control over that character as well by just pressing a button and the AI walks towards you, or to that direction. and when you have that kind of control, that maybe some more enemies will be spawned for some more chaos?
on the edges of the screen there is some blur, but I really didn't like that part, it kind of hurts my eyes looking at it.
but you did a good job of making this.
