That was a lot of fun- I thought the mechanic was pretty neat and there was a lot of depth towards the end :)
I did hit a minor bug; your physics update interval doesn’t seem to be the same as the timeline update interval, which means that if your computer is struggling these can come out of sync and your pieces don’t make it to the right position before the timeline enters the next grid. But I solved that by not running in fullscreen :D
Even so- I had fun getting to the end :D
