labyrinth (LabyrinTwo)

LabyrinTwo - a two-player maze duel for the Commodore 64 (ACME + VICE), in the same spirit as rabbitc64.

A fresh maze is carved every round on a 39x23 lattice where the walls are exactly as wide as the corridors. Player 1 (joystick 2, or w a s d) runs the corridors toward the green diamond exit while dodging the roaming colored enemies. Player 2 (joystick 1, or i j k l) rides the corners of the walls with a blinking cursor - fire (or return) spins the four wall pieces around the cursor by 90 degrees, reshaping the maze in real time. A spin is denied while anyone is standing in one of the four slots.

The options screen adds two optional twists:

• runner gun - player 1 shoots a bullet with fire/space; a hit enemy respawns on a random cell after a pause.
• spin cooldown - each spin starts a recharge; further spins are denied until the draining bar on the status row runs out and the readout flips back from wait to ready (the cursor also dims while recharging).

Screens: TTG intro (ported from rabbitc64) -> main menu (play / options / rules / controls / credits) -> game -> win (back to the menu) or game over (fire retries with a fresh maze, m backs out to the menu).

Build & run

make deps       # macOS: brew install acme vice
make build      # -> labyrinth.prg
make run        # build + launch in x64sc

Test builds can boot straight into one state:

acme -DAUTOPLAY=1 -f cbm -o labyrinth.prg main.asm
# also: AUTOOPTIONS, AUTORULES, AUTOCONTROLS, AUTOCREDITS,
# AUTOWIN, AUTOLOSE; add -DFORCEOPTS=1 to start with both
# options turned on
