The visuals are quite nice but the interface is not clear enough in my opinion :
- it took me a while to understand the game was actually a tower defense
- I didn't understand how to change the color of the dice before dying during the first game
- Also, sometimes when putting my dice on the colors, it wouldn't change
- I often accidentally grabbed several dice at once although I only wanted to take one
So, highlighting some parts of the table when you have dice in your hand or highlighting the dice you're going to grab when you hover over them would make the game much more easy to understand and play.
The music and sound effects are fine.
As for the gameplay itself, it is indeed fast-paced. However, the decision-making felt too easy for me because I felt like using only white dice was a viable option.
The main reason for this being the fact that chaning their color takes too much time, and also the fact that colored dice didn't seem to affect the gameplay that much.
