That is just a neat game with so much potential. The final level is clever. I only realized each AI brain was different part way through that level, so maybe indicating that to the player earlier could be good (it's possible you did indicate it, but I just missed it :p ).
This is the first game I've played this game that I want to see a follow-up to. The art is excellent, the puzzles are fun, and the brain switch mechanic is super clever.
Great job!
