It was a lonng discussion between us whether to have the number oriented on the same face, or based on the input during the jam. Maybe adding a "flip indicators" option would help?
Also, the time to move I wish I could've implemented a tweak able delay, but when I made the animation they were pretty tuned to the delay that we set, and I didn't have time to change the functionality of that. That was a thought of mine too though.
The thought to undo a move didn't even come across our minds, that would've been a great addition.
I'm glad you liked the levels though and they weren't too hard.
Thanks for playing!
