the radio is rigged to play PONPON SHIT 90% of the time i think

Autumn 2007. Me and my parents were on vacation and I met a boy there, who showed me this game on his Nintendo DS Lite. I thought it looked really cool and always wanted to have it myself, but I didn't know the name.

Jumping 15 years into the future, I now know the game's name, but don't think it is cool anymore. There is no tutorial, so good luck finding out, how Dungeon Dice is played.
