This game is really fun (and a bit challenging for me, which I like because it keeps me entertained for hours).
The only thing that bothered me a little was the controls at the beginning because I didn't know how to use them or how to change them, but then I got used to it and was able to complete it. The tutorial is quite entertaining and really teaches you well, and the code and design are decent.
The soundtrack is incredibly fun and cute.
The enemies remind me of old Flash games, and I really liked that, especially the ghost that follows you directly. It really made me go "wow," and I was truly impressed.
