I liked the concept.

I enjoyed the idea of this game. I sort of wish there was a smaller practice jumping area as it took a lot of tried to even get up to the first platform.

Cute character. The art and music are well done. The gameplay is okay. Great job!

It's cool!  But I'd like more controls such as jumping again or moving when Mr. Slime is in the air. Otherwise, it's a little hard for me.:)  BTW, an error popped in the browser.

Great game! It's cool that you introduce more mechanics.

Got stuck on a bit I swear it's impossible - Bah!

Nice and fun game! Becomes more and more interesting as you progress more. I eventually gave up at the stage after the ice after the fourth time restarting. 

Maybe a counter of how many retries are left would be helpful. I was also expecting the mouse drag to be in the same direction as the one I wanted to move to (not like a sling), but quickly got the hang of it. It was very convenient that I could "center" the sling anywhere by just dragging from that point.
