Unblocked Quicksand Hell

I made most of this game like a year ago, when it was just blue-gray blocks jumpin around. I couldn't work out a good aesthetic where the floor was rising but DOESN'T affect the environment. It was only recently when I was thinkin about something completely different an I thought OH YEAH, DUHR, SAND. SAND IS EXACTLY WHAT THIS GAME NEEDS TO BE ABOUT. Then I came back n finished it, made the guy a desert babe.

Quick Sand Hell

One o the early ideas I had was that it was a small girl trapped down a well, and the game was called 'Let's Get Outta Here'. Another idea was that you were on a sinking ship and water was flooding in.
I got the MAIN idea from a level in Jak and Daxter 1 where you're in this silo and this black poison business is rising up, but there's LOADS of games that do a similar idea. I took most of the code from Mighty Tower, a game I made last year which was mostly based on Meat Boy.
