That damn door is going to be the end of me, I know it lol. Thanks for reporting that! I'll get those patched up ^^
I wasnt even sure the level could be beaten, First I put all the boxes down the chute which softlocked me, then i built a ramp up to the laser but angling it at the blue point only made it light up and nothing else happened, then i brought another box up there and it made the reflector flip out and shoot out of the level XD
