Nicely done! The game feels very polish and smooth! It really have that zelda feel and I like it very much. It's a bit sad when it ends so abruptly at the shop, but I guess accident do happens.
A minor bug/feature is that the enemies and coins, hearts respawned when going through rooms. I forget how the old zelda games behave but it sure is a way to abuse the system that way.
Anyway, well done! I am looking forward to later levels!
