A fun idea! Good opening screen and tutorial / controls information. Well done on the UI in general. Character select was cool! Loved Mr Sharky! The art style was consistent, and the music was catchy. Excellent work making the dice stand out so well from the environment so we always knew where to run to for our weapon.
Some constructive feedback - getting the dice to actually land on a number other than 1 was difficult, but this was key to gameplay. Improving this would be a great step forward!
