Immiscible

Private equity firms are trying to steal all the oil and water from the planet but their pipe drones are weak when in the opposite substance.

Push and rotate pipes to link enemies for higher points (and more upgrades).

For Godot Wildjame 72, Light and Dark with duck bonus.

Score Details: When a linked enemy dies in the vulnerable state (in it's opposite substance), it increase the points by 10 for the next enemy, accumulating, so an enemy worth 40 points base (which is all), if you have 4 linked in a row, the first gives 40, then 50, then 60, then 70.

If you link a chain and destroy them consecutively, you get a massive bonus.  I wanted to put in a lot more bonuses and upgrades but, surprising no one, I ran out of time.
I hope you enjoy it, thanks for checking it out!

"Immiscible" is the term for things that don't mix.
