Good start but a lot of stuff needs work for it to be enjoyable in the slightest.

First of all im not sure if any of the difficulty settings work because their is no visual tells of which you are playing and if they do im not sure what they affect. 

Secondly their is no introduction what so ever and you have to grasp the game by yourself.

The health bars don't seem to work, either that or hit detection is really bad.

The game tells me  to use the 'B' key to interact but i don't know what with nor do I have time to find out do the constant onslaught of projectiles.

The art and music isn't the worst I've seen but definitely nothing that was worth sticking around for.

I also don't see how this fits the jam's theme but oh well.   

That all being said with some hard work Little Dungeon could be something worth playing and i sincerely hope you work hard to improve it and take my criticism on board.
