Needing to press 2 keys together is very unintuitive, it might have been better to use a t op down view instead of isometric to avoid this. It's a nice puzzle game and easy to understand, just a shame that the movement mechanic makes it frustrating.
It was initially top down, there was a need to show three faces of the die or it would have been too slow to grab in your head.
I'll add command options, thanks for the feedback.
