Fun concept reminded me a lot of anti-chamber, I went smoothly through the experience except during the blue line puzzle
( it took a while before I thought the downward arrow meant something) and in the end where the final wall require a square I forgot at the beginning,
Overall a nice and short puzzle game with good control and interesting and fresh mechanic
5/5 put it on favourite
strangely the game could be improve by removing some of the first level because the game is too long to start I was going to quit if the 3D wasn't the next level

Yes - I'm aware fo this - but not sure what is causing it. I'll fix for all version of game.
