A pretty interesting way for the use for the theme, the art is pretty neat. The level design was also pretty good, in particular when I was doing the forth level I was wandering that was the gimmick here until I saw the missiles, while the piranha one stomped me pretty hard.
I did encounter a bug, like when the lil guys enters the portal they get stuck mid shrinking animation and the only way to fix that is to grab them away from the portal to complete the level (they count as lost)
In the end a pretty interesting game~
