You just have to play the game normally. The timer auto-splits every time you change a level, so if you want to take a different route (for 100% for example) you'll have to customize your segments. After your first successful run, the mod will save your times in a file called "poc.run" at the same directory as the jar file. Now every time you have another successful run, your best segments will be saved, and if you get a new PB run, everything is saved.

How to customize your segments

As this is a tool I created specifically for the any% run, it's a little bit difficult to customize your segments. You'll have to change the "new.run" file INSIDE the jar file. This is the file format: [number of segments] [name of first segment] [name of second segment] ... [name of nth segment]

Final words

I doubt that anyone will ever use this, as this game is pretty much dead. But if you have any questions about this program just ask them on this game's forum. And keep in mind this is a tool I created for myself only so a lot of things are hard-coded or hard to modify because I could just change them on the go. Bye!
