I have been looking for a chain reaction game I played a few years ago. You clicked on the screen and things started exploding differently activating others blobs that would explode in some other way activating more etc etc.
I have been searching for a while, trying some keywords but I couldn't find it. Also not by rating sorting, it was such a fun game... :/
Aaah thanks Gantic, I'm not sure if that was the game I meant, because it is so long ago since I played it. But it probably is, it has some sort of the upgrade system I remember
