I really like the idea of this with solving the puzzles quickly before the lights go out :) I wish there was a restart button? As soon as I started level 2 I immediately realized I messed up, but had to wait and watch as the darkness consumes me...
I'm not sure if this was just me, but was it intentional that you pressed a movement and have to keep pressing it to move, rather than the normal holding down in that direction? Very fun idea though!
