Key & Compass presents:
Killing Machine Loves Slime Prince
by C.E.J. Pacian

Killing Machine Loves Slime Prince is a Z-machine interactive fiction game written with Dialog and is © 2023 by C.E.J. Pacian.

In this odd sci-fi romance where your options are defined by your inventory, you play as a biomechanical and taciturn killing machine whose solar sail has just crashed on the Eighth Moon of Forsaken Edge. Your love, the Decoy Prince, is dying. Your quarry, the True Third Prince, is somewhere nearby. He will not escape you.

This solution is by David Welbourn, and is based on Release 5 of the game.

SPOILERS AHEAD. Reading a walkthrough prematurely can sometimes diminish one's enjoyment of an interactive fiction game. Please make an honest effort to play the game before reading this walkthrough.
