A solid prototype!
I like how the dice is expected to roll around like a ball, that's a good idea, and it could perhaps make a great game.
Although in this game, there were a few problems... The biggest of which is that the physics is a bit janky. The dice feels super floaty, and it's really hard to tell where it's going to land. Those are both critical for a game like this to feel good.
Also, probably related to the gravity being too low, it doesn't feel like it matters that this is a dice. It sometimes rolls or bounces in a way a ball wouldn't, but usually it just rolls in whatever direction I press, without the orientation of the dice really mattering at all.
Overall, it was fun little game.
