Super cool idea and well executed. Congrats on making this in just 48 hours.
I really enjoyed my time with this game. The puzzle of having all rolls known was a cool take on the theme. I really appreciated how you managed to use the randomness of the theme while taking out the random! That feels really clever.
With more time, I could see this system being fleshed out into a full game idea. You've really hit on something here. As it is, it gets a little repetitive after a few battles, but that was all I needed to "get it" and enjoy the game.
Be proud, you made a super cool thing. Keep making games!
