Seems neat! Is there a mailing list to get contacted once you finish the game?
I like how lazy it is to move and attack :p At the beginning, I was searching the attack key everywhere only to find out that there's none. Maybe there're could be a way to explain that. I.e. A simple tutorial where you move, get your sword, and attack a frog or whatever ;)
I like the retro look with the modern nifty details. Good job overall!
