Cool game! The art style isn't bad eighter, the only problem is that it lacks consistency. Like some objects are drawn in prety high res (raindrops), and others are really low res, (boulders) some objects have hard black outlines (goats), and others have none (raindrops). the whole thing is 8-bit style but the menu has high res fonts. I think it's worth paying attention to this kind of artistic consistency since it can make the difference between a very nice looking game and an "ok" looking game.
Anyways, nice job keep it up! :)

A really underrated entry! The menus and UI were amazing, I've certainly taken some notes there xD. The gameplay itself felt really smooth, with some great use of post processing the put an emphasis on getting hit by one of the rocks. The only area I see needing work the game's art, compared to the rest of the game. Given a little more work I could see this being a great title post jam. 

Best implementation of this idea I've seen yet.

But maybe make the boulders fall faster and the hitbox of the player smaller. It was a great Idea to introduce other obstacles like log (even thought I don't get why they won't just fall down :D). An other idea to make the game increasingly difficult would be to increase the speed according to the current height.

Great game! The graphics and music fit nicely with the game. Quite fun to play!

And it's nice that you added support for every OS.
