Greyscale Wormhole Operator is a dodging game where you control the gravity of a black-hole-like object in order to help a broken spaceship dodge cosmic debris. To learn about the game and how to play it, click the "Go To Guide Room" door on the title screen.
Even without music files, this game is just too large to be played on weaker devices (such as mobile devices, which have problems with larger Scratch projects). If you want to play Greyscale Wormhole Operator on a device that can't run the full thing, then check out the Save Code Simulator (https://scratch.mit.edu/projects/546305472/), which doesn't have any of the customization this version has, but as a result of this removal it's significantly smaller and thus can run on weaker devices. I'd normally put a changelog here, but this game is less than 100 kB away from the Scratch project size limit, so it's not gonna be getting any content updates (though I'll still fix bugs/glitches if anyone finds any). I'd say this game has more than enough content already. That being said, on November 27, 2021, I did add a button to the finishing screen for the Custom Mission Simulator that lets you go back and review the properties you set.
