I had fun playing, it was a good jump’n Run, good Job. I especially enjoyed the concept art :P

The only quirky thing i found was dashing into edges with goop on them which insta kills you, but that didn’t happen that often. Also i love how smooth the controlls are, was actually one of the better ones i played :D

I also have a few suggestions you could try:

1. maybe make the camera a bit farther away, so you can see some of the more distant edges better. Especially below the player.
2. checkpoints would be nice :)
3. you could add some more enemies like something that comes out of the poison or a enemie that shoots itself thorough the air like bullet bills. those would also be usefull for more platforming

Great and simple platformer! The movement feel smooth and responsive, I especially love the air dash mechanic!
Well done!
