This was really fun, ended up playing it for quite a while! I really like this interpretation of the theme, and being able to reposition the towers ended up creating some really fun / frantic situations trying to get the dice in a good position when I was about to die.
A bit more control over the direction of the dice might be good (e.g. with the cursor) but that's a minor nitpick. The difficulty at the beginning was nice - but it begins to taper off a bit as you progress.
I really enjoyed playing this, great job!
