I expected this game so much! this is very fun! but there are some problems...
1) the text is unreadable, I will add a picture in the discord server so you can see (its me, aradarbel10!)...
2) the menu for changing key layouts is a bit broken. the buttons are overlapping and its hard to click the right thing. I am not sure if you were able to do something about is, maybe its just my browser... but I am happy about the current keys so it dosent really matter.
3) the mouse can scroll the window (move the camera), and this is a really nice effect, but I think when I move the mouse to the edge of the game window the camera moves too fast and is had to reposition the camera just slightly.
4) this is not really a bug, but I'd like to see hold mouse for shooting longer. right now I need to spam the mouse button, and this is annoying everyone around, and me. a feature like that would create a better game experience for me, personaly.
overall, the concept is very cool! I just love the way you change colors, and the way everything works. keep this good (and fun!) job! and I am waiting for your next jam ;D
EDIT: unluckily, I didn't post a game to the jam, so Im pretty sure I can't vote..
