Cool concept for a game! It would've been interesting to see some of the other options once your reborn, but I made it through with a straight warrior build.

Some of your enemies are positioned a little awkwardly on their battleback and end up looking like they're standing on the wall, but that doesn't affect anything other than the visuals.

Neat game! 

Game literally expects you to survive a first battle against 5 strong enemies without having even told you anything of how battles work. Learn how to balance your battles.
