People have been having issues so this was probably also messed up by scratch 3.0 like everything but I really don't care enough to try and fix it. On the title screen, you can press number keys 1-5 to change the night. Note that doing so will also set your location to the start of that night. You may also use the R key on the title screen to reset the night. You will mainly use the mouse to interact with objects. Use the WASD keys to move around in the crawling sections. Hold Shift to run in the crawling sections. Spacebar is used for the Mascot Audio and the Flash Beacon. Tasks are told to you by in-game audio.
I do not fully claim this mine. I simply fix some bugs on the game to have better gameplay. Credit goes to @ManManBoyBoyMan
