Yeah, sorry about the weird graphics glitch. I still have no idea what's causing it and anything I do just doesn't stop it for some reason.
For the platforms, I was considering adding a timer for it so you couldn't spam it, but it just made the game much slower and limiting the amount of platforms per room would add more puzzle aspects to it, but I just didn't have the time to try and balence that stuff out.
Hope you enjoyed it, and glad you found the secret (although I accidently deleted the roofs off all the rooms trying to fix the graphics bug so it was suppose to be slightly harder to find)
