I want to add Little Alchemy as a game but I have a question about submitting it. When I submit the run to go along with the game can I submit a run where I create X amount of elements instead of all 580?

Any run that beats the game should be sufficient, you don't have to do a 100% run to submit a game request.

Yes, you have to say what the rules are in the video and complete the game

IT IS OFFICIALLY ON SPEEDRUN.COM
