"Is this the way out?"
I won with a mage, then won a second time with a warrior to see the difference and killed the minotaur this time and immediately won 3 levels, I like that it's beatable with a strong reward instead of invicible.
The game is super fun, it looks good enough overall although a few higher res elements clash a bit but more important it controls well, movement feels good and the 4 trials are all great and all different. Invisible enemies are always cool. The warrior and mage do play different enough in the context.
I think there's a rare case of a dead enemy leaving an unreachable tile, which the previous comment seems to confirm.
This is a great entry, thanks for sharing.
