Defend the ship at the bottom center by typing the enemy callsigns. The physical keys follow the
colorForth 27-key cluster. Early waves use only the letter layer. Later waves start mixing in the
symbol and number layer. Space toggles the layer at any time.
Space toggles ALPHA/SYMBOL mode.
Backspace or Esc clears the current lock so you can retarget.
The top-right key on the alternate top row is intentionally blank, matching the reference layout.
Ship lost
Score: 0
Enemy names start as plain words built from the letter layer, then evolve into mixed callsigns with symbols and digits.
Switching layers cleanly matters more than raw speed once later waves arrive.
