Fun game, feels like Zelda 1! I beat the elephant and tiger and didn't realise there were more bosses until watching the video - then went back to beat the others. The art and music were great and had an nes feel.
I enjoyed exploring the world and seeing the different transformations and secrets (I would never have found the slime!) If I had one complaint, it would be that all the enemies and bosses feel pretty similar, and my strategy never really changed - but its amazing you managed to get so many done in such a short time in the first place!
