Cool game, It was really fun to play. 

I wouldn't use browser alerts to inform players about clicking the window though. When ever I see a random alert from any site I always take a step back. I would just say it in the description or have a note on the title screen.   

Absolutely love this!! Perfect use of a minimal control scheme and lots of fun!! The only thing I'd suggest is maybe adding an input to restart the level, so you don't have to wait till you fall if you realize you already made a mistake. Not a huge problem, but might make a players a little less impatient.

Great work!!! Super fun to play, fantastic design and gameplay.

Oh, this is so much fun! The last stage was extremely difficult, but I cleared it by kicking the scaffolding in front of me instead of going to the back.

The music loop stopped while I was playing with it.

Just having a sprite for the main character would have made it look very different. But it deserves more rate!

Cool!I like the idea of switching between different forms.
