You have some interesting ideas for this game, and it would be cool to see them fully implemented, like being penalized for bullet collisions. If you continue working on this in the future, you might want to move the health bar, and maybe shrink it. I found myself hiding behind it too much, where I was blind to attacks.
Thank you for commenting and playing my game! :D Im really excited for the future of this project i think it can really turn out great :) I know the Health Bar is too big i accidentally set it to the wrong size last minute and ended up with this, so don't worry its not a design choice :P
Glad to hear you liked the game though ill definitely check your game out have seen it around a lot and am very interested in it :D
