The rules are simple: try your best to make the game in 3 hours, but even if you can’t - still submit it, you are allowed to go overt! However, only games developed in 3 hours or under are eligible to get the 1st place. The time only counts for building your game, that is, any coding, making sound effects/music, art, and other assets. Writing a design doc, coming up with ideas, compiling your game, or making the itch.io page for it does not!
compiling...extracting...uploading...same thing in this instance.
