This is loads of fun! Such a simple idea, yet very well executed. And quite tough too, though admittedly I played with a track pad on a mac – so not the best hardware to be precise. Thanks for doing a build for that platform by the way!
The different orientations, sizes and positions of the walls makes for interesting choices in the placement of lasers, as well as forcing you to always be mindful of your surroundings so you don't get stuck!
The music is fun and fits the pace and tone of the game (which I would describe as "Aaaaaahhhhh! Aha got you! Aaaaahhhhh")
Well done!
