Nice! Love the music - very retro 2D platformer ;) great sound effects too. Smooth character movement. Really good job. I had a really, really hard time beating the boss at the end! ;p And then at one point he just disappeared! I still don't know what happened. I just walked in and he was gone, and the door was open. I tried again and he was there again. Weird lol anyway I eventually beat him for real. Nice game :) Good job!
