Outside of the good graphics and overall presentation, this is a pretty frustrating game, and arguably, one of the most difficult games on the SNES.

This is immediately felt when you play the first level. The enemies respawn very frequently, you're really slow, and the worst of all is the double jump and how they decided to go with it.
Double jumping quickly turns into a hard to control glide, and combined with the wide areas you need to jump through, together with badly placed enemies, be prepared to die and repeat the levels a lot.
These issues become more and more evident and annoying with each passing level, turning this into an unsatisfactory to beat game.
