Love this entry!
At first I didn't think there was going to be a lot to this game, especially since you explore a lot in the beginning of it. Then I found a boss. And I also started to remember to use the interact button! (It would probably be nice to blink or float a button next to things you can interact with).

Once this happened, and I beat the first boss and gained my new ability, the game kicked into overdrive! I beat the spider boss first and got my double jump. Then I found the goblin king, and was convinced he was holding something cool, much to my surprise! The last challenge was the wizard and boy, he was pretty rough!
I loved the simple, yet solid, game play in this. The most nitpicks I have are really just with the art and music, or lack thereof.
P.S. Very impressed with the file size of the game too, especially zipped!
