This looks really cool! The isometric aspect was awesome, however, the map can get kinda confusing, since depending on the camera some walls dissapear and make it quite hard to navigate, but is not much problem.
One thing I didn't like was that when you get hit, you have to start from the beginning, and I got hit. A lot. Maybe restart in the same room or a room behind, because having to repeat everything all over again can get kinda boring. But despite that, it was a really cool game!
