Cool game! The take on the theme isn't very creative, but that's fine, because the platformer movement is really solid. The idea of "challenge coins" is really good. Minor nitpick: it wasn't immediately obvious that you can wall jump of the level border too. I would maybe smoothen the difficulty curve a little bit, it's giving rage game vibes too much sometimes right now, but tbh that's understandable given the time constraints. Anyway, solid game!

So, for this one I really want to give some awesome feedback. I loved the movement of the character and how juicy everything felt (even with the lack of proper art). Also the music felt very fitting and made me groove to the beat. Yet as with every game I want to give some tips and critique:

- No sound. While the game is very juicy itself, it feels dead. And that is because it is mute. Please add music, it ain't that hard in most game engines and it is so worth it.
- The levels were WAY to hard. I barely could finish any of the levels and everything was so unforgiving. 
- I know that one hadn't to strictly follow the theme, but the game just felt like a generic platformer in my opinion. The timer was just so annoying and it felt like the theme was a second thought. This is my biggest problem

In total I think that the game excelled at the execution but failed with creativity. But still it is a great template for a good platformer. 

No joke that was one of the most enjoyable games of this jam! Had me hooked start to finish. Solid idea and execution, maybe lacking a bit of SFX

That was fairly enjoyable! The game felt a bit like Super Meat Boy and I like how you unlock mechanics over time. I think the only think I'd change is mapping 'W' or the Up arrow to jump instead of space. Outside of that, the movement felt really good!

nice movment and the game makes a lot of fun

i love how slooth the game run and the cube jump good game

i showed this to my senpai and he approved

awesome game, very fluent movement and felt very snappy. love the extra challenges

I got stuck after getting the second power up and spamming space bar I couldn't see what it was xD

fun difficult game !

wow very tight platforming. super meat boy vibes! unfortunately i am awful at platformers and struggled, but it was great fun nonetheless ;)

good stuff man. Level design is hard... I like it

could finish it beacause im' to dum-dum, really like how squishy the player character feels, didn't really get where the loop theme fitted but when the clock pointed on 00:00 and went back to the first level my mind was blown away, really great concept for a game, I encurage you to make a full on fledge game out of it, it's just that great
