I enjoy this game a lot!
Here's the bugs I found:
-The player can stand outside of the map from certain areas
-The player can sometimes stand on the side of a die tower
-If a die tower stacks too high, newly spawned die will stack overlapping other die
-Using missle or heart blocks while the die is airborne consumes the die without granting its effect.
-Way way unbalanced enemy to die ratio around 7000 and above
