I really enjoyed this game, and could totally see it becoming a full sized puzzle game! The idea is very solid, and gives a lot to build off of.
I never really figured out the sweet spot to start/end the recordings, so recorded self would typically end up sitting still for a "cycle" while another box came through and fell on the ground. But I'm sure that would get refined with more time. I would also suggest putting an indicator on the first levels controller scheme which button grabs the box. I spent a bit longer than I probably should have trying and failing to use the grip button instead of the trigger to grab the boxes. And the final thing I noticed was when you paused the game, the recordings still cycled, so they would get thrown off if you didn't time the unpause right, or just restart the level.
Overall really good game though! Would love to see a more of it!
