I like the fast and reflexive gameplay. It really locks you into a certain zone and gives it a unique feeling compared to the sea of other 8-bit platformers. It is fucking hard though. It's also just a reskin of Wonder Boy, but I find this game's visuals much more charming, and the music is worlds better.
