I think the idea is fairly fresh, but I found it somewhat punishing, because sometimes the roll outcomes resulted in a situation where I couldn't do anything to save myself (all options resulted in me dying). I think you could deal with that in two ways: rig the RNG or allow rerolling the dice (but still using up a roll).
As mentioned in other comments, I think it could help if enemy movement was more predictable because there's almost no way to make strategic choices otherwise.
Also, a minor issue: the music was restarting with each level restart, and that felt a bit annoying.
On a positive note, I liked the music and visuals, and the game has a fair bit of polish. I think if you deal with the stuff I mentioned you'll get a really nice game.
