For the life of me, I can't beat lvl 15 on the alien campaign. No matter what approach I take, I can't get more than 6 or 7 kills on the Raze soldier. It's a little frustrating.
Fun game, but some slightly wonky physics -- and it'd be nice if the game held off from computing success until things stop moving. I've had a few times when waiting another second would've gotten me a success.
4/5 for concept alone. Would love to see it expanded with a bunch of new perspectives -- maybe a scientist (everything's mass & forces), a businessperson (everything's monetary value), an athlete (everything's an arena), someone sleeping (everything follows dream logic), different children's perspectives, &c. Could be the foundation of a really excellent game.
