Whew, I'm getting a little sweaty from this game.
This is a great idea. However, I was too nervous when I could already see which face I needed to put the dice on, but even a short press on the directional button would turn the dice away too much. Maybe some kind of slow mode could have been added with holding the ctrl button. The game is similar to golf, so it might lack its putter.
Also, I later found out that the game waits until the cube remains at a 0 angle to the floor. My current angle is wrong, but the face of the dice is the right one. Usually developers wait until the dice stops and then look to see which face is closest to the top. Although you could have avoided this if the answer box was a simple outline rather than a square pressed into the ground.
However, I would love to play a reworked version of this game.
