Ive used it, and I highly advise against it. The vast majority of development on roblox is free to use assets. and near none of roblox studio will ever translate to real world development. I think the real issue here though, is that the likely-hood of you developing a "good" roblox game in 72 hours is extremely slim and your chance of getting a high place in this jam is extremely slim. just learning godot in a day and using that for this jam will greater your odds of more people in this jam playing your game.

That is certainly not true, and also I never planned to use Roblox for this jam, i was just seeing the perspective of u people.
