Yea I've noticed that too before, it pretty much is useless
If the game laggs, you get impossible ingame times, impossible to beat and almost 30s faster than rta runs, that's why we can't and won't change that.
No, it's actually been confirmed - laggs do change the in-game time for the better! But that's not enough to beat records just by tuning down your CPU and it's hell to play
Emulators are usually exactly as fast as their mobile versions, but lags etc influence your gaming expirience way more when using an emulator.
I don't think Nameless cat is in need of an own Discord server, but if you want to talk about different strategies and post your progession - you can do that perfectly on the "Mobile speedrunning discord"!
Have a grand day!
Welp the only real trick I'd know of is the 1-7 Wall glitch, the rest is practice, doing levels over and over again, watching good runs helps too!
