Here's my honest feedback for you, hope it's helpful:
- Art style is pretty nice.
- Resolution for WebGL version is way too big, I couldn't really see the whole game screen on Full HD monitor. Height was the problem. You should probably stick to 600-700 px high window on web.
- As for the gameplay, I didn't really get how to play the game and use the dice that I got so some in-game tutorial or step by step explanation would be nice.
- Transitions between turns last too long (when you click on the red die)
- Bug: If I die and go back to the main menu then press play again I'd immediately get fail screen and would be again taken back to main menu.
