This game has more strategy to it than might seem at first glance! I failed a few times by not being able to defeat the final level because of my dead-self being too powerful. Quite the twist that the main bosses are created by the player's own failure.
There are many factors and details to think about in order to optimize time. It can for example be a good idea not to pick up power-ups before running out of sanity, to minimize the strength of the dead guy and being able to pick them up before battling him. Original and fun concept and mechanics.
I accidentaly clicked "Leave dungeon" multiple times. When dying so suddenly and often, it's easy to click any of the options while frantically clicking all over the place (a confirmation would be great, or having the leave-button somewhere in a top corner).
It was also a bit annoying to click through all the rooms after every death. But I suppose this was meant to imitate that a new wizard is entering to see what happened, logically starting from the beginning.
Art, sound and music was satisfying. Good work :D
