Hmmm...
I didn't particularly like this game, it looked great at first... but it sorta went down hill.
I couldn't even get him nearly puking since it was too easy. Plus as mentioned by another, there is nothing to avoid. What should be avoided is something that'll make the play puke, as well as too much food, or even something that makes it so it is harder to swallow (meaning you don't swallow it all it stays, making the process harder), etc.
The characters head also seemed too big in my opinion, making him half the size would help as well.
You had something going, but I must say that it didn't quite do well for me.
