I love the new and interesting mechanic! Exploring mechanics and ideas is what jams are all about in my mind, and you really pulled off that idea.
I feel like its a mechanic that has sooo much potential but is JUST missing something that would bring it to perfection. Maybe some higher quality UI, or having time fully stop (so you can pull off awesome combos and so on!)
Overall a very unique system I could see being made into an incredibly fun super-hot like game.
Great entry, hope to see more :)
p.s. - Im not sure if it was my device, but the audio was REALLY REALLY quiet? I could barely hear it even at 600 % browser volume
