Thanks! Yeah, I was hoping to make at least 10 levels but I ran out of time.
No wizardry involved. I was able to make this quickly by using the built-in GameMaker physics. They have soft body physics for making water in the engine, so it started off as a water gun but I didn’t like it so I goofed around until it was “sticky” enough to act like slime. All the solid objects were basically like flipping a switch.
The toughest thing was figuring out how to make it play a sound at the right times since the “water” doesn’t have actual collision events you can use like the solid stuff does. I rigged up something that detects abrupt changes in the velocity of the blobs of slime.
I never did figure out how to combine the slime together when two blobs touch, but that’s something I’ll continue to look into.
