I have two questions:
1. How do I activate Two Player Mode?
2. How do I reset all my high scores?
Two player mode is a bit weird, yeah. To activate it, set up the game however you want to play it, and then instead of hitting the Enter key to start the game, press 8 instead. There's a very specific and weird reason behind this, but I won't go into it unless you want.
To delete high scores, you'll have to locate the INI for the game. It can be found in:
C:\Users\(your name)\AppData\Roaming\MMFApplications
It'll be the file called "73mp.ini". You can open it in your notepad app. Look for the lines that say "PacHighScore" or similar and delete them, then save the INI. Or you can just delete the whole INI as well, but that will reset all your settings too.
Okay! My bad on that. I've put out an updated version which should just let you choose a 1 or 2 player game now while in the menus. Just hit left or right when "Start Game" is selected to choose a 2 player game.
Sorry again about that! This was stuff that was halfway in development and just got mucked up when I made a version for Itch.io.
