The Lost Dungeon

This is my first 2d platformer. Defeat enemies and overcome obstacles over the course of 3 levels and steal the artifact worth a lot of money

Three modifications:

Entirely unique environment, enemies and music with a different tilemap set (it takes place in a desert)

I coded different modifications throughout the game (gravity invert, infinitely spawning enemies, etc.)

Giant bossfight at the end.

Please comment on anything you want to see improved.
