Thanks for the feedback.
You saw what there's to see mostly, the point of the game is clicking around to spawn creatures and then watch them interact with each other.
I understand the appeal of upgrades and progression but this is more of an aquarium thing, or if you want to go for score in "Time Attack" clicking a lot is the best way.
No need to apologize :D
Maybe I'll make a mode where it shifts more towards that clicker definition, with an upgrade progression to help the creatures' interactions. I'm getting some ideas :)
