That was an interesting game. Not going to lie it was a challenge to figure out what was going on even with the intro instructions. I played several times and found it was a real scramble to figure out what to do, and what did what. Maybe I'm just bad at it. But I will say I did see several death animations for the black goop. From Freezing to melting in to green acid, and exploding all very cool. I feel If I kept at it with trial and error I would figure it out eventually. I am impressed by the complexity of what you made, the setup is clear and funny, but it lacks direction. All and all still a solid game. Good Job.
If you can maybe leave more detailed instructions in the description above. I would like to play your game again with a clearer understanding of what I am doing.

Very solid game and concept for the amount of time. I'm impressed with the depth of the gameplay. It was incredibly difficult however with the very short amount of time you have to figure things out and mess around with the environment, some way to figure out the idea and controls before being put under a time constraint would have been really nice
