An interesting concept that's pretty well executed overall. I particularly liked the animation of the enemies.
There are some things I believe could be improved:
- UI/Buttons could be a bit more intuitive (I found the dice with a cross really confusing at first, maybe have a separate "End Turn" button)
- In the later levels I found myself in situations where I was just skipping turns until I got a good enough dice roll which just wasn't very fun. At times, having a dice took away from the strategic element, rather than add to it. Some sections would probably work better if you had a different movement system than a dice (e.g. a deck of cards with different numbers on it that you choose from)
- Changing the colors of the tiles/backgrounds between levels would've made things pop a little more.
Good job, overall!
