A decent start
Well, it's good you've got something working. I know it's hard when you first get going to make something that turns out the way you want it. A few suggestions for making it easier to play -
Some simple on-screen instructions. It took me a minute to figure out what I was supposed to be doing, and what I could do.
Maybe make the character a bit smaller so the level can have more breathing room. I found that I fell into the quicksand on the second screen almost as soon as I arrived because I didn't have enough time to register what was going on when the screen changed.
