Oh. . . You're right, though. I was confused by the .exe extension, I was totally inattentive.

I did play! My final score is 17000, last level was pretty long trying things (maybe it is just me wanted to sleep, huh). The design both visual and audio is elegant and simple, with nice animations and effects. I like lighting puzzle! Rotating cells is also gives a room for interesting combinations. The transparent walls was little confusing for me, the rules they work lay down for me only in latter levels. Actually this is really great puzzle, and one of the best entries in this jam! This was fun to play!
