It's a short, but fun game with a good charm. It had a pretty low performance on my end, causing sometimes dying from lava while standing on a floating block, but that might be just the way of Unity.
There was only this situation where the block got stuck in the wall, and I couldn't push it out again. https://imgur.com/ftvcr6b
I tried to undo, but that didn't worked after getting the Diamond that made me longer.
