I agree that playing the game explains it better than the introduction screen.
However the game is a bit of an odd one here. It's supposed to be a puzzle/strategy game but you have a lot of randomness to really control it.
I found myself mostly looking for colored dice to place in the general area I meant to expand rather than paying attention to the value of the dice.
Spam clicking while the dice are being generated also kinda breaks the game, I had multiple dice in the same place, but I understand that kinda defeats the purpose of the game.
Overall it's a cute game that fits the theme, well done.
