The idea is great and intriguing. I really think there is a great game behind it. You should explore it further once the review period for the jam is done.

I can't seem to figure out how to move? I can only shoot little blue orbs to the red planes. :(

Took some while to wrap my head around how to play. Potential game to be a cool turn of super hot.

when you move to the shard, the shard starts rewinding, and you are like an ant sniper perching on it.

I'd say there are much space to improve:

1. An aiming support system. Since it is not super-tight-accuracy shooting game, it would be nice if there is an auto clipping to the nearest shard of your mouse.

2. An audio feedback on hitting would very greatly enhance the satisfaction in shattering panels.

3.Player controlled time winding speed. Maybe it could turn into a puzzle game about shard flying angle and moving sequence if you can wind the time forward and backwards.

4. On level design side, I think at the start of a level, you should be able to see multiple panels at once, since it requires some waiting before you can move to the shard, it would be best if we can use that time to aim and shoot other panels

Great work on your first Jam!

+outside the box game design, simple mechanics that are entertaining and fun

-annoying music, sensitivity defaults to zero (confused me for a while since mouse movement did nothing)
