The concept and execution are both fantastic!
Love the dual controls, 'let there be chaos' indeed :) Tried it using a controller but maybe mouse and keyboard would have been better. The difficulty is punishing, but in a good way I think. Unfortunately I got stuck at level 8 (I just can't seem to figure out what triggers the lasers, am I just too slow?), but I think I'll come back for another crack at it later!
Nice touch that you have a practise mode, even though it took me a minute to work out how the main menu works, but it is very clever. Music was decent and the graphics were crisp and clean and made reading the levels easy for the most part (figuring out which pressure plate/switch triggers what was a bit trial and error though, but maybe that's intentional).
Great game!
