Slime Simulator is the perfect way to play with goop, and not make a mess. It's still a bit rough around the edges but overall I am pretty happy with it. Here are the instructions: NOT MOBILE FRIENDLY!!! As of the moment, you have 3 slimes to choose from. 1) Pick the slime you want to play with 2) To make the slime stretch, click the space bar 3) To make the slime swirl, click the "S" key 4) To reset the swirling, click the "R" key 5) If you want to go back and pick a different slime, click the red back button.
This game is heavily based on Thrift77's Slime Simulator Game. You can play that here: https://scratch.mit.edu/projects/530255141 All of the artwork was traced using a stylus on my Chromebook. This is Pixel, not vector. Please share this project with others, and feel free to comment any suggestions.
