Art style is okay. Looks like an old cartoon which I find very appealing. I noticed it doesn't take much to fall straight through most of the clouds, not sure if that's the point or not. Would help a little if you could jump just a tad higher, especially if the space bar was for jumping instead of up.. Kind of feels like this was almost thrown together and not reviewed enough. Music or even sound effects would have been nice also, especially 40's style, like mickey mouse lol. That's almost what this game feels like to me, art wise.

Simple but charming visuals. I especially like that you created an idle animation for Onionhead (though I don't know what triggers it, sometimes he does it sometimes he doesn't even though I don't touch the keyboard) The controls are smooth

However there is no sound and you can sometimes fall through the clouds. I also could not finish the game. I went up all the way up to the big circle thing in the ski (the wormhole?) but even if I jump straight into it nothing happens.

For these reasons I can only rate it as 2,5 / 5 but I hope I can revisit and rate it higher once you got rid of these bugs.

I can't complete the game because you can fall through one of the clouds.

Overall, I believe the game isn't ready. It was kinda fun for a few minutes, but it's still a little touch and go with the collision. For example: Sometimes when I was just walking on a cloud, the character would randomly fall through for no real reason. Music would also be a nice touch. And although it was fun for the first while, it can get stale quite fast. I think this game needs to go through a little bit more development before it can be called a game.
