I loved the look and feel of the game! I think there should be a timer or buffer on the shield to avoid spamming. Also, it's easy to sit in the corner of the screen and spam the shoot and defend button so a way to avoid that would be good too.
The corner thing is a huge flaw with the game, yeah. I was brainstorming ideas to mitigate that but didn't really have time. If I update the game, I might add a feature that paint bombs fall on your position every few seconds, although I'm not sure how I would convey that naturally to the player
