Nice, quiet fun. Congratz on the first public game! The only part that is a bit in the way is the collision area of the clouds, which is a bit too large. I think it is nicer if these kinds of collisions are "inside" the cloud in these scenarios, and if you want them to be that large, you can just make the cloud sprites bigger to get the same effect :D

Great game. I had fun playing it!

You make the use of HTML canvas look so easy.  It keeps making network requests for assets that are already loaded. Not a big deal, but I would optimise that. There's no audio unfortunately. Wen sourcing assets its sometimes hard to get art styles to match, but this works really well together and ties in with the theme. Well done.

Good little submission to the jam, well done!
10/10 would win with W again

Very nice calm gameplay :D

If I keep mashing the W key it becomes very easy. Needs a difficulty arc.

I had fun playing your game!

Reasonably easy game to pick up and play.  Straightforward controls.  Not very dense obstacles allowing me to advance pretty much as long as I want.  Would love to see maybe an autoscrolling camera that I have to stay in frame of or more dense cloud cover.
