Poor level design
The level design is crappy. Half the levels you can win by just waiting for the sand to rise. You get four for the physics and graphics.
Reviews for "Quick Sand"
Pretty Good
It's a good game, but the difficulty is fairly steep. Add a pause button... I liked it. Tweak and optimize, and you have a game.

I've got nothing to say
yee
I think those "easy" levels where the only thing is sit and wait are designed for the lava mode and the speedrun, i agree with the wall jump, its akward.
an interesting concept
however, one of the issues i ran into is that oftentimes, you can easily just let the sand do the work for you. in situations where the only thing you need to do is scale a certain area to reach the exit, you can simply sit there and let the sand bring you to it.
