Loved the sound effects and art. I could totally see the brush swinging as a cool mechanic for analog stick, or a motion control. The difficulty curve was pretty fair. The only thing that felt strange to me was that i wanted to left click to make the brush stab and extend my reach a bit, it seemed like I should be able to after having used the right click to dash. I like the idea of hiding power-ups as well as health pick-ups to make looking for secret areas motivational, it's always a great feeling when you hear that a-ha sound in a game. So satisfying I think it releases endorphins. I can tell that you have been practicing making games something that I commend you for. Well thought out, good job.
