I haven't played a great puzzle game in a long time. This game just resetted that counter. :D
Apart from good graphics and controls, what I'm mostly praising about this game is its level design. You are playing in one big level composed of many rooms, but your abilities in the beginning are very limited and you can't reach them all. As you play you slowly acquire different powers, each giving you a different perspective on the rooms, allowing you to get where you couldn't before. Finally when you get the last power, you enter the endgame state which gets insanely interesting. No room is seen the same now. Hardcore out-of-the-box thinking and big-picture thinking is required as all the rooms are now more connected than ever. You'll respawn very often after several of your strategies haven't worked. And just when you think you're stuck... you'll find a solution that was right in front of you the whole time. :)
Thanks for this lovely puzzle experience. I enjoyed every part of it. And it very much reminded me of a similar flash game called K.O.L.M. I'm very sad that there is no audio at all, otherwise this game would be a masterpiece of this jam. Well done. Really well done.
