Great art and soundtrack. I think Level 3 could use a different one to make it stand out and the background staying static made it hard at times to tell what direction I was going. The sliding mechanic is cool but I found myself mostly jumping over or shooting enemies since they would be in the air or I was on a short platform without much space to slide on. Some feedback about how long the invincibility lasts would be nice too since sometimes the sliding animation lasted a bit longer at times. I got stuck to the side of platforms a lot and since there's no way to recover from it I have to just let go and die which was annoying. Also shooting on moving platforms was weird since the platform would move faster than the bullet so I was able to pass and interact with it.
