Another LUA-based game hack from 10yard! This one’s a mashup of two perennial arcade favorites, Galaga and Donkey Kong. Each level has a chevron powerup somewhere in it. When Jumpman picks it up, he’s joined by the spaceship from Galaga. The jump button is also the fire button! Further, the ship’s shots are piercing, and can destroy more than one enemy with a single blast.
You’d think it’d make the game much easier, but the difficulty of the game has been subtly increased to make up for it, plus controlling the ship as well as ol’ Jumpy is a distraction, so it’s still pretty challenging.
In addition to Donkey Kong, the hack’s github page notes that it works in Donkey Kong Jr. as well!
