is there a reason to restarting checkpoints where you do? like at 23:16 what's preventing you from skipping the whole zone and restarting it the next? unless the area won't load.
Speedrun strategys like clipping through walls or skipping sections are widley used and most speedruns would not be possible without them. Its not cheating
This is probably how a real cat would go saving the world. They dont like other people wasting their time, and all this is just such an inconvenience to them that they'd get it over with as fast as they can so they dont have to deal with it any longer.
