Rated it! I'm gonna reiterate on what I said in the pages comments:
a) the player moves VERY slowly and the jump hight is super low. I understand this is part of your interpretation of the theme but it feels very sluggish to move around. Work on the movement.
b) the graphics are cute, but as a fairly amatuer artist myself I can tell you that simple is ALWAYS better when you don't know what you're doing. Try using simple shapes, don't add detail where you can't make it look good. Another thing about the graphics is the resolution: A bunch textures look super soft and smudgy but some are very sharp, and that bizarre contrast (I assume something that has to do with the way you imported them into unity) looks really wrong. Your shading is also very inconsistent. Something to work on.
c) as for color work, there should usually be a big contrast between the foreground and background so they don't interfere or mix with each other: if the clouds (the background) are white, don't make anything in the foreground white as well (like the player) it happened multiple times that the player's white mixed with the cloud and i couldn't tell what's going on.
d) the UI shouldn't be so big, it distracts from the game and makes certain areas hard to click/see. pause button should be small and on the top corner, the health should not block half the screen, etc.
I'm sorry if I come off as a little harsh here, I just say this because I believe if there's a will there's a way, but only if you also have the will to take criticism and improve for next time. Hope to see you compete in more jams!
