Nice atmosphere, cool visuals and huge dungeon! I was not able to find out, but collected 40+ something crystals :D Controls are ok, I liked the random buffs you get from the crystals it spiced things up a bit. Unfortunately for my not so common 21:9 display the game UI didn't scale well so i was guessing my remaining lifes etc. For beginners this is huge project to do in two weeks but you did it anyway. Don't stop, continue developing :) Congrats!
