I don’t speedrun on mobile but for what I have seen mobile players do I think you should be able to pull off some tricks. It might just be a bit harder to develope good routes and strategies.

hmhmmm true i think crouch jumps could be a bit tricky. especially getting them consistent at the start of an level. since on pc you just press w and d for example right after you spawn.. which is not really possible on mobile... if you can always 100% have the joystick in the right direction so w and d are 50/50 yes. then you can do it too but its tricky. thats how it works i think . i dont play on mobile

Platform advantages are very common among speedrunning, unfortunately, its a fact of life
