Ya know, the silhouette of that bird kinda reminds me of the picture on the crates in Quake. Doesn't it? Anyway, we're not talking about quake; we're here for Commander Keen! Ok check this stuff out.
These cheats work for Keen 4-6. (I don't really care for keen1-3, if you haven't noticed, so I won't display cheats for them either.)
To activate debug mode in Keen 4 and 5 type A + 2 + ENTER (keen 6 always has debug mode active)
F10+B = Set border color (1-15) F10+C = Number of active objects F10+D = Record a demo F10+E = End current level F10+G = God mode F10+I = Free items F10+J = Jump mode F10+M = Memory usage F10+N = No clipping (don't fall off the bottom of the level map!) F10+P = Pause (so you can capture the screen) F10+S = Slow motion F10+T = Sprite test F10+V = Add 0-8 VBLs F10+Y = Display secret areas F10+Z = Ends game (doing this in the world map causes an error) F10+W = Warp to a level (0-18)
