This game frustrated me in a weirdly good way. I kept wanting to go back and try to get farther than I did last time. I found the art style great, being a fan of pixel art myelf. A bit more contrast on some levels would've been nice, especially since you have to focus so hard on the screen, but it didn't hinder my experience. Some music would've gone well with the fast paced gamelplay, but in general the audio was great. The sound effects give a lot of feedback, and picking up coins feels good.
Overall, it was a good use of the limitation and a pretty fun game!
