Thank you so much for giving my game a shot! I'm really grateful that you attempted it, and really appreciative that you enjoyed it! That last cube that you had trouble with, is a little finicky. It works just the same as the others, but the interaction system I use for interacting with those cubes is kind of janky. In order to fix it, I would probably have to unravel everything and start from scratch. I have another system I'm attempting to implement, but no promises for an update at this time. If you would like, feel free to attempt it again, but stand back a little ways from the cube and try picking it up with a held left mouse, click. Getting it over the ramp, might push it into your face but it will go over. I'm sorry for the hiccup and long work around, I do appreciate your time regardless. Thanks again!
