I don't think there's any issues with the run starting like this for escape%. For hard% we need to see the gamemode selection, but for this one we just need to see the hand move for the first time, and the white screen when you get to the tunnel
I don't think it's that much of a necessity, but I think it would be fairly easy to provide saves for each category (for example, a save with a maxed car). They are saved in "%APPDATA%\Macromedia\Flash Player#SharedObjects\ZDRG7V36\onemorelevel.com" if you are playing on Flashpoint.
Hi, I too am new to speedrunning and was introduced to this game a couple months ago by Jimma. I talked about this with him and we think it would be more challenging to introduce getting the car upgrades as a part of the (at least) 100% runs. It would add complexity to the decisions that are done in the run (Should I kill myself to get an upgrade and try to win back the lost seconds or keep going until I cant, which upgrades should I prioritize in any given moment of the run, etc)
