Patch:Cheat codes

Cheat codes are sequences of keys pressed simultaneously that provide an in-game effect. There are two main cheat systems, Keen 1-3 and Keen 4-6 (Also used by Keen Dreams.)

Keen 1-3

Here cheats are a always accessible during gameplay. They can be changed or disabled on their own pages. The cheats are:

God mode: Make Keen invulnerable to hazards
Free items Give Keen stuff
Map level skip Walk through a level on the map

Keen 4-6 and Dreams

In Keen Galaxy most cheats are only available in debug mode which can itself be considered a cheat. There ar some exceptions such as the free items cheat. Keen Dreams doesn't have a debug mode and all cheats are available all the time. The debug cheats are also known as F10 cheats and a number of them were used to debug the game as much as enable players to cheat.

The switch -nowait used when the game is run will skip the debug code. The cheats are:

Cheat	Effect
Free items	Give Keen stuff
Win game	Win the game and play game won sequence
Boss key	Show a false command prompt if caught playing Keen at work
Border color	Change the border color
Object count	Display information on how many 'things' are in the level
Demo	Let player record\save a demo
Exit level cheat	End current level
God mode	Make Keen invulnerable to hazards
Item cheat	Gain items and points, similar to Free item cheat
Jump cheat	Let Keen 'fly' while jumping
Memory cheat	Display information about memory usage
No clipping	Let Keen fall through solid tiles
Slow motion	Slow the game to a quarter speed
Sprite test	Display information about sprite graphics used in-level
VBL cheat	Add VBLs
Warp level	Play any level you wish
Secret reveal	Show hidden passages
Suicide	Kill Keen, game over

F10 cheats and Debug mode

These cheats can be accessed when debug mode is on. Each requires the F10 key and another key to be pressed. For patches that relate to debug mode, including those that disable it as a requirement for F10 cheats see Patch:Debug mode.
