I don't think this game really works. I think the choice to include a heavily reaction-based combat system in a puzzle platformer is a bit bizarre, but I don't think I would have minded it if there weren't a bunch of other gameplay issues.
First, I'd end up repeatedly fighting the same guy over and over if I stayed on the bottom floor too long, which makes it frustrating to experiment with the puzzle and figure out how to turn off all the lasers. The combat also seemed pretty luck based, with it being incredibly hard to win if the circles were spread out in an inconvenient way. I did manage to turn off all the lasers, but for some reason I still died upon trying to exit, and I couldn't get past the first level.
However, I do appreciate the quick and to-the-point tutorial for the combat system, and besides my complaint about its difficulty, I quite like the idea.
