You can chloroform a butterfly!
The graphics are childish but endearing, and they do not distract from the true focus of the game, your imagination.
I have always been used to a very structured, orderly way of going about most video games and this is a very healthy break from any sort of pressure most games impart on you.
There are action levels and puzzle levels, I find each to be very enjoyable, you can summon whatever you want, whenever you want, for whatever reason you'd like to use it for.
The game will not be fun for you unless you make it fun, this example summarizes the entire game and its wonders:
Early on, one of the levels asks you to catch a butterfly in mid-air by whatever means. I summoned a ladder and chloroform, and knocked the butterfly unconscious!
If that doesn't sound entertaining to you, I don't know what is.
I love scribblenauts!
