This was a pretty good platformer, but I agree with everyone else that it could follow the theme better and that it was unreasonably difficult. Some enemy hitboxes felt slightly too big. I thought it was cool that you added a secret underground area though.
Also, for some reason (maybe i'm just a masochist lol) I decided to keep going until I won the game, and after an uncountable number of deaths and rebirths, I finally reached the ledge leading to the button. I could feel the power in me, and I knew that destiny must have brought me here, to reach this button, to end the world...
No offense, but it was kind of anticlimactic :(
