Since GOG has not included any manuals, can somebody post the keyboard controls for these games.
I figures out how to launch the ball and operate the flippers, plus the game tells you how to navigate to a table, but I cannot figure out which Key to use for Tilt.

I believe the ALT keys are used for tilt.

[Spacebar] tilts for me.

Controls are lack of consistency.Each game have different key mapping.

Dreams 1

CTRL=flipper
Enter=forward nudge
Space=plunger

I recommend you modify mapper.txt

change to

key_enter "key 32"
key_space "key 274"
key_down "key 13"

CTRL=flipper
Space=forward nudge
Down Arrow=plunger

mania,fantasy,and 2 work same manner in default.

Illusions need change to
key_enter "key 274"
key_down "key 13"
for same control.
