Geometry Dash is a side scrolling game sort of like some 2d mario levels are. I think allowing speed hacks can encourage players to actually beat the almost perfect speedruns. This will also make the competition feel endless because you can always go faster.

Hacks, cheats, game genie codes, etc are usually not allowed in speedrunning. Speedruns are intended to be on un-modified versions of games. That’s just how it goes.

But, if you’re insistent on pushing that, you need to discuss it with the community and mods of the game in question.
