Very fun Idea, some kind of a non number UI could be cool and like others have said more levels would be nice to keep it fun. That being said it was still a fun game and the music and sfx were good.  Nice idea and good execution.

Simple but good. I would tune up gravity slightly to make it feel slightly less floaty, and other people have mentioned the small level pool, but it's good!

Really fun concept that i'd like to see expanded. I feel like making more of a big deal about what's going on with the timer would make it more rewarding and add a level of fun anxiety, but i love the high speed minigame feel to it.

Also truly random levels meant that a few times i got the same level repeated, and one level i only saw on my third play!

The concept is pretty cool! I'm glad you got this out there and made it! Now you can add some more levels, or section the levels somehow and made it world-based, or whatever! There are lots of directions to take this, given the good foundation you've lain for it. 

Personally, I like less floaty jumps, and my gut reaction was that it wasn't clear enough that I was gaining time, but after ten whole seconds of play I was very on board with the experience and thought that it all added to the feeling of recognizing what to do in a short time-frame (Warioware-esque?? Perpahs that's the direction!).

Dunno if it was on purpose, but sound started off by default for me (I guess I just assumed it didn't have sound because it was a Jam entry and I tunnel-visioned on the gameplay, but my point is that it really adds to the experience, so maybe take it as a sign that you might want to emphasize it more or start off with sound on).

The overall game was fun and addictive, with good Music and SFX which created great feedback! The asset pack was also used nicely, and overall made the game look clean and polished. While the lack of levels gets boring quickly, the clock always keeps the game interesting.

Fun and plays nicely, but I wish it had a bit more variety in the levels. It ended up being the same levels over and over again but with a different time limit.
