The way it works, is like the GMOD/SFM Sword in the Stone Collabs on YouTube. A character of your choosing (official or fanmade) has to attempt to pull the sword out of the stone with comedic results, but ultimately fail to pull the sword out. For example, your character(s) could imagine what they would will do with the sword if successful, but in reality fail, and simply go to hilarious lengths in trying to get the sword out. You may use more than one character, but you're limited to no more than 5. Characters COULD pull the sword out, but it'd have to end up back in the stone at the end of the collab submission to stay consistent between entries. It doesn't HAVE to necessarily be animated with flash, hell, you could use still pictures in Windows Movie maker or whatever sort of video making/editing software that you're most comfortable with. The maximum amount of entries I am accepting will be around 50, but I don't think I'd get THAT many. Anyway, there is going to be quality control involved, I won't accept any purposefully half-assed entries, and the video quality for the entry itself MUST be at least 480p. There is a limit to only ONE entry per person, unless otherwise specified.
If you are interested in taking part, please send me a note in DA's private messager and I'll send you an invite to the discord server, where the sprite pieces for the collab will be available.
