Could be because you replied to a random unrelated comment, instead of commenting on the post itself, or because you could’ve just looked it up easily, or maybe people thought you were being snarky somehow (especially since you were replying to somebody)
You need to beat the level to upload it, and I suspect it’s a clear check upload - however, separately, the game tracks first clear and world record after a level is uploaded.
My understanding is that the goal is to clear every beatable level that doesn’t have a first clear (and some that have been cleared by known hackers, but I think those are all cleared legitimately already)
People are ignoring that just the act of playing the game can be fun. On top of that, getting better yourself or pulling off certain maneuvers can be fun, or even appreciating what the opponents are doing. I had a lot of fun playing rocket league with a friend, even if outmatched, and getting scored on an opponent who pulled off an aerial into top corner made me appreciate what they just did.
Maybe also take a page from dwarf fortress players: Losing is fun!
Funnily, there’s something like this in hollow knight too - you tap the button to use a spell, hold to focus. In HK though, there’s an extra bind you can assign to cast a spell instantly.
Cleverly cheesing rules is up to the game master’s discretion, while transforming into a whale sounds like a very reasonable, if overpowered, interaction, the peasant rail gun wouldn’t fly in most campaigns. Not that it makes it any less hilarious.
