This actually isn't a bad game and i like it. It could use some music (I'd like to make something for you if you want?
You could also so with a sound for the crush/stomp.
I like the way you can hike up pretty much any vertical surface which is cool :)
I found it odd that you used the glitch in the way the character sprite is unstable to collect the coin in the block. interesting, but I like it funnily enough!
Get some music in there for atmosphere, add a level timer, maybe some power ups and you've got a Mario beater bro!
