This was realllly well done. I got stuck on World 7, but I had a lot of fun figuring out the puzzles. I love how simple it is (as far as the controls go), but you have a lot of leeway to layer on new mechanics for more complex puzzles. I assume this was an accident, but World 6 was very easy to solve because the portals were right next to the robots (there might also be no collision on that level? I couldn't get a robot to die).
My one small piece of feedback is that some of the sound effects are too harsh (such as pausing, clicking, and switching worlds). I can't quite place it... maybe it's too much bass? But I think a puzzle game like this would benefit from more subtle sfx.
Aside from that though, I'm very impressed with this, and it fits this jam's theme perfectly. If you continue with this, I would love to see more levels and maybe some pathfinding from the robots so that they can walk through doors without me having to precisely click their path. Great job. Keep it up!
