All-in-all I gave the game 2 because of its lack of diverse enemies and its plot(ending mostly)
The jumping was a little slow, to slow.
The ending was very anti-climatic and dampered my feeling of sucess. You could have made some of the stages more diverse(looking like they were going deeper into the ground) I couldn't give you a higher score due to the cookie cutter platformer format. sorry. I hope my review was helpful or useful.
