I just bought this game + the sequel and was pretty interested to learn and run these games. And as it looks everyone has to learn it for itself. Is it the case or do you have a discord, forum, TS or something else to talk and discuss about? And how optimized are the games? Greetings, Ognilrak

That is actually kind of the case. The RKS series doesn't have it's own speedrunning discord as the community as a whole is actually pretty small, and there's only like, 3 or 4 people actually active. You're free to ask questions for RKSF and I'd be more than happy to help you out. RKS is a little more out of my territory, but I do still at least know a few things about the game. Another thing is that these games are -mostly- just optimizing your movement. These aren't glitch heavy games, so by watching other runs (high and low level both) you can learn how the runs are done and where you can optimize things. Of course, there is still RNG and glitches involved, but the glitches at least are minor parts of the games. With the exception of a glitch called Jetsliding in RKSF, but even then you can get a good time without it.

As for optimization, these games are really optimized. Despite the small community, the games have had a lot of work put into them and the WR times are really difficult to beat.

Welcome, and I hope you enjoy running these games~
