while it may not seem like it, each character has different abilities, dr fetus is a high jumper, gish is slightly less slippery it seems and so on. if you can't do something and you have high enough band-aids try another character.
I really liked the non browser version of this game, so when you made it browser and added on some bonus content, you can't imagine how happy i was. And not only is there a decent amount of bonus stuff, it's all pretty solid. Sadly, a lack of achievements will probably draw some people off, and although it dosn't lower my experience, i would have liked some. Good Job! :)
