I think expanding on this project game is a great idea. Please add mouse support to click the choices. Also, having "secret titles" (such as by level, attribute distribution points, etc.) would be cool. I would also suggest making the end guy MUCH harder to beat... with his own category (#5). This way, players can keep getting exp in the level 4 category. Heck, make a bunch of increasing difficulty areas. Just cut and paste, right? :-)
Making one of the kill mommy choices actually do something (i.e. - rewarding ending) would be good. Otherwise, it smells like a dead cat. 2/5 - Because I was dumb enough to keep trying to look for the ending.
