Installation:
Backup the main.scm file currently in your Vice City data subdirectory.
Put this mod's main.scm file there.
Put the american.gxt file in Vice City's text subdirectory. It still has all the old entries so you don't have to make a backup of the original.
Playing:
Start a new game.
After a few seconds, you'll find yourself at the lighthouse. Walk inside and stand in the pink circle.
You can use the following keys:
left, right, down: move block.
up, sprint: rotate clockwise and counterclockwise.
jump: block drops instantly (keep this pressed if you want to end the game).
Score is kept by your money. It is not reset when you play again inside the same game.
The level is indicated by your wanted level. So if you want to start at a high level, you just need to get a high wanted level first.
