Congratulations on your first Ludum Dare entry, and you started in hard mode with a compo!
Its a fairly simple idea, but it is executed pretty well, and fits the theme well enough. I'd have liked for your background tiles to be seamless rather than obvious tiles, but thats quite nit picky.

It was an interesting idea to have the main character grow bigger as they descend - they are huge by the time you complete the level, lol.

awww my dude got too big haha pretty cool though!
