Ok, this is actually pretty clever. Best use of the dice theme I've seen so far.
It's quite interesting having different abilities but you can only use them depending on how you move, as well as enemies changing their threats based on their movement. I think the skill ceiling on this could be quite high for clever strats. Maybe you could even expand it to more than six sided die.
I don't like the controls though, I really want to move with the arrow keys, and having the other buttons next to the movement keys feels prone to accident. I also wish you didn't have to commit to a move before attacking though, feels a bit cludgy.
Also I think theres a bug where sometimes the assassinate skill wont let you move the attack cursor, but nbd.
It was nice how the first few levels kind of tutorialize you as well.
I think I'd enjoy this as a full game if there was a fun story and characters, probably abstract the dice rolling a bit so you can have actual characters, and they can all have some kind of dice that represents their personality that shifts around as they move. Just my thoughts though.
