The Roblox side of this project is no longer being worked on. Thanks for playing! Our Roblox games have now been made open source. You can give credit to us if you use our game's code, but you don't have to. You can edit our games by clicking on the '...' on one of our game pages and then click 'Edit'. This requires a PC or a Mac as Roblox Studio is not supported on other platforms. You will need to re-add sound effects as well. You can find the assets and other development info on our GitHub. (OSSimulation/Resources). If you're downloading older versions of WinXP Gui Test, please note that some versions have a PlaceId checker. You will have to remove it in order to fix those versions. You can tell if it has a checker if it says "Windows is not genuine". The Roblox side of this project was discontinued due to major stress and anxiety on me. It turns out having a popular game can do a lot on my mental health, so I have stopped working on it to ease it.
