Are you the same serponge from geometry dash
Yeah GD was a good time, It helped me learn about game design actually, so I can't be thankful enough!
Also yeah, GD is pretty crazy on that aspect, I've rarely seen a level editor go that far in term of possibilities and customisations, usually it's either you can do lots of stuff gameplay wise (minecraft), or you can do lots of stuff art wise (little big planets I believe) but GD mixes both!
