Love the art style! the background is very pretty! and the Puffkin's are adorable in the into bit! Few minor bugs some of which could be interesting. 1.) if you hold "D" and jump at a set of stairs you speed jump all of them you can get a longer jump distance. 2) Also encountered the same getting stuck on the wall bug, saved my self from death a few times with that one :D.

But it's a really fun game all things considered. 

Fun lil platformer, the pixel art looks nice and the jumps feel good.

The only issue I really had was that you can very easily get kind of stuck in the wall hitbox (which you can then jump out of, sometimes), which leads to some very strange behavior. I'm not sure if this was intended or not, honestly.

I kind of wish the fluffy guys didn't turn into dots when in the level, since they're cuter otherwise!

Nice, I was able to play through and save all the puffkins. It could use more game mechanics and level design but you can tell it's coded well (love the background) and the pixel art is great.
