Cool game! I liked the music, very 90s and very catchy. The art style is nice, but there are some inconsistences in it

 I think that a lot of the backgrounds/floors feel out of place and look a bit odd.  The spike trap obstacle looks much more retro than the rest of the art and doesn't really match.

A lot of the obstacles that look like they should be on the ground, move at a different speed than the ground, which looks strange.

The game is very challenging, but I think there are some things which make it a bit too hard. There's a lot that the game doesn't explain. It's not For example, I had to figure out that the dash ability can safely destroy all the pink obstacles (I think?), but not any of the other obstacles. That's cool, but the game never explains this to you. Maybe at the beginning of each stage there could be some sort of list of the obstacles you'll face in that stage and what their weaknesses are. 

Also, the jump can be difficult to use. I had a hard time predicting where my character would land, so I would often land on top of the obstacle I was trying to jump over and die anyway. Other times, I would hit the obstacle despite being in the middle of a jump.

Thanks for submitting!

This is so cool! It really reminds me of old flash games from the 90's, which is nice. Speedy and fun.
