[Help] Name of the game, puzzle game with 'corridors'

Hi,

i'm looking for a game of which i can't remember the name. It is a 2d puzzle game where you have to push rotating corridors from yellow to blue (i think), when all the corridors are blue you go to the next level. everytime you push they change color again. As there are more corridors it is a puzzle as you need to figure out what the right sequence is. I also think there is some enemy you have to avoid but i can't quite remember. I use to have it on disk..

Thanks for the help!
