First of all: I like the key-mechanic of the game very much and appreciate that you took the real theme and not like many others said "the game is minimalistic", no in this game the player is a minimalist, which is awesome. Also the animation of the player is very good and underscores the movement mechanics. The only major issue is, that I got stuck in an area where I did not know how to proceed. Also it is fairly difficult to do precise jumps. Other than that you every now and then get stuck on edges, which is a bit immersion breaking since the player is a ball: I would not expect box-colliders with respect to that. Some sounds would have been nice as well, even just simple ones when the player moves and or jump. 

I want to mention that my critique is much more on a high level and I am well aware that this is a game jam. I think that the core concept is cool and that the visuals are solid. 

Cool project: keep making games!

i can't even explain why, but i found it oddly relaxing? usually when i pick up the game and feel it's more "physic -ky"(?) i always expect trouble, but it actually felt really nice. the upgrades being a bit katamari is pretty cute too! The arstyle is great, and only bit of feedback is to maybe make the cactus? upgrade a biiiit more visible, i didn't notice i got a new power until my bf gave me a heads up (he liked it a lot too btw)

otherwise i think it's a pretty solid game,  just wish it was a liiiittle bit longer,  but i'll probably try what the other commenter said and try to complete it without upgrades for now lmao  

i wish there were more games like this, ive been pretty tired but i can just melt in the chair and just play it with one hand while i dissasociate

I had a weird enjoyment out of mastering the heavy momentum of the Sisyphus bolder. It did feel sticky in some spots like corners where I had to move a little away from the wall in order to be able to jump. I also couldn’t fully understand the wall climb momentum, it seemed like sometimes I’d ascend further than other times. I liked the added challenge of trying to beat the game without any upgrades; it took a few tries but once I mastered the movement system, it became a speedrun challenge for me lol I actually found it way harder to beat the game with the upgrades and couldn't beat it when trying to get the mushroom upgrade, maybe I don’t know how to fully use it or didn’t see a path to take

I liked the animations and the idea behind the mechanics. Something that I would improve if I were developing is make the blob/rock/log (Whatever it is) a little bit faster. As far as the wall jumping "special ability" thing, I could get up some walls but not others. I don't know if it's just me being bad or something else, but that's all. Great game so far! Rolling up walls is smart, and for my circle shape in my game I was actually considering something similar when prototyping my game.

I like the animations of the blob, and the concept of building up momentum and rotation to climb up walls was a lot of fun to master. Controls could be better as sometimes it would get stuck on corners of the environment. I would love to see this concept fleshed out further.
