For those of you having trouble with the cyan ceiling room, try and find the room with the green thing on the floor. The solution to that room is very helpful for the cyan ceiling room.
This game is, in short, not very good at all.
The level design is generic at best, reminding me a lot of Super Meat Boy or Mario. What doesn't help is the fact that the tiles of the level seem to have no relation whatsoever to the level itself. The hazard tiles have horrible hitboxes, making the game almost unplayable in some places, and the music is nothing but an annoying 5-second loop.
I'm sorry, but this is just bad.
There's a neat but subtle little trick you can use on the boss: when your "clone" follows your teleport, he turns blue for a fraction of a second. While he's blue, he can't hurt you.
One slight problem I have with this game is that it's sometimes hard to tell which way the beams are pointing. The difference between an emitter and a lit receiver can also get confusing sometimes.
Ahaha you might be right, but I can still use it for a sequel! :D
