Nice little brainteaser. Took me a while to understand what the goal is but after realizing you need to get the rolling head dude to pick up the coins so he can enter the green portal and this is achieved by moving the pink and blue portal around.. It turned out to be a decent little puzzle game :)
Completed several levels, all of which offered a good amount of challenge. Not too much to make it frustrating but not too little to make it feel like a no-brainer.
I like it
