Since there are no rules available, i used these points to start and end the run :

• the moment we start controlling Grace
• when Jack's box closes

It's my first run i'll submit but there is a lot of improvement to be had here, maybe on routing, but mostly movements, item placements and such (the screen change lags end up adding a significant amount of time so this could be optimized as well). I'm not aware of any useful glitch so this is a glitchless run.
