I was a tad worried when there were only secret medals. Luckily, it was pretty easy to find them. I do have a lot of problems with this game. First of all, how are you supposed to jump on a slime once you've weakened it? I can't jump up that high! I must have missed something in the instructions. It actually has decent gameplay, though.
I think the best part is how good the graphics are. You get a lot of space to jump around. But again, I don't know how to play this thing well. A more experienced person will like it more. Then again, I have over three thousand game reviews, boy does that make me feel bad.
