Congrats on making your game for this jam!
I've already seen this concept a handful of times in this jam, but I like that you give the player options with three dice. That's always important that the player is given adequate chance to react to the randomness of dice. That, or make choices about how they want to use randomness. As always, the art and presentation is appealing and well done. Good job!
I think the levels fell a bit flat for me. The would either be done in a few turns because the key spawned in a direct line and the door was close by -OR- they took forever because either or both objective was tucked away and I sat there for 10+ turns just rolling for the right numbers. I think an objective that required less precision and allowed for more reaction would have fit better, such as defeating all the ghosts or collecting X gold. It's fine as is, but needs additional tuning to reduce the number of "do nothing" turns that can happen when you're sitting next to the exact and can't roll a 1.
Cool idea, if a bit frustrating at times. Well done. Keep making cool games!
