This is a very interesting premise for a game. So you choose the floors you want to basically complete, really cool.
As for the gameplay, I think it could be improved. Since we can use the mouse to shoot with the bow and arrow, it would be easier to move the character using WASD in that instance, so maybe we could have both the arrow keys + WASD for movement?
Loved the sprites on this game!
Would like to see it be expanded for sure! :)
