A really fantastic submission. Reminds me of other "programming" games like SHENZHEN I/O or Human Resource Machine. Really sharp graphics and audio, and I'm blown away by the time manipulation / replay feature. I'll be pulling the project to dissect how you did that in Godot for sure! My only gripe would be that the physics are sometimes not quite deterministic. On the final puzzle with the arm to pick up the green triangle I tried the "correct" solution, only for it to not work (green triangle got stuck on the goal, preventing the arm rotating). However, going back to the start of the timeline and simulating from the beginning made it work. I think this could be mitigated with more playtesting and changed level design though. Overall, really nice, I can imagine it being a very successful tablet game.
