Hum even more awesome glitch on level 39, the turret at the bottom lvl was shooting a cube that i was holding. I was just behing the platform where the exit is and the cube started flying with me and i glitched through the ceiling and a portal to finish in front of the exit ! In fact its like real portal game ^^ lots og glitches but still awesome game, i finished all lvl normally and tried to discovered other bugs way to end it like in a speerun or smthg.
Great game overall !
Level 38 must be fixed i think, adding a bit of grey wall at the left of the floor with the 3 switches. With a good angle i was able to come back with the 3rd cube direclty without activating the middle left wall.
