I'm glad you enjoyed it! The dash mechanic is really rough around the edges. I wrote in the tutorial that you can dash when in range of neon signs but I should have better included the tutorial or made a better tutorial in general. I'm definitely gonna improve the particle system sometime in the future because after playtesting I saw that the lag is a serious issue.
It's also pretty much the first real 2d platformer I've ever made, so I haven't really gotten the physics and movement completely down yet.
