Lovely graphics, challenging game! I included it in my Game Maker Toolkit’s Game Jam compilation video series, if you’d like to take a look. :)

Very good art, and a fairly neat concept. I feel like the game is a little too unforgiving, though. The idea that they can't collide with each other feels like a step too far to me. Also, maybe instead of all walls meaning death, maybe you could place hazards to avoid (spikes, lava strips, whatever suits your fancy). I also encountered a bug where B.O.T. would just rocket off for no reason and die without me having touched anything.

First of all: great visuals and great idea, works very well !

One thing really that can be problematic (despite the absence of sounds, but you where alone and it's a Jam, so it's not a big deal) is that the camera in centered on the ball and not on the two elements at the same time. You can lose your cursor like that, and, obviously, kill yourself.

But hey ! The game is good despite this, nicely done !
