Difficult! I stopped playing at the "jump over the car" level. A "skip level" button would be nice here :)
Graphics and sound were minimalist but clean. The colors fit the game and were instantly readable (which is important in a game, where you need to know what will try to kill you in the next 10 seconds). Some music would be nice.
The gameplay was interesting, but difficult. I think I liked it more, when there's only one doll to manage.
The theme... hmmm.. I guess the objective of the game was to save them all. But I couldn't do it, so was it actually on theme?
Oh! And I see this is your first jam! In that case- congrats on doing the hard thing- making it to the end with a finished game! Because, especially for a first-timer, you did pretty good :)
