Hello, I was going to do a 2-player run for SMG with a friend. I didn't see anything for nor against using Co-Star mode, and I would like to know if this is allowed. Thank you!

I found another 'restored' version. I played the one Bluely sent yesterday but it was broken when I tried it. The one I discovered has been updated more recently, isn't broken from what I have played, but it doesn't save your data, which really isn't a problem in speedruns. https://www.roblox.com/games/5608847199/Adventure-Forward-Star-Savior-RESTORED-IMPORTANT

This doesn't answer my question. I knew that already, I'm asking specifically about 3D All-Stars IL Runs.

I saw on the SM3DAS speedrun forums that IL runs will not be listed there. This leads me to asking; if I did an IL run using SM3DAS, can I submit it here instead (as there would be nowhere else to post it afaik)?
