Q/A or ↑↓ = up/down · O or ← = brake · P or → = thrust · P, enter or c = fire · space = bomb
1983 mode is the original, warts and all: P only fires on a quick tap (hold it and you just thrust), O or I brakes, and anything on the bottom row (Z to M, space, shift) drops a bomb. no laser button, no second chances
touch: hold the left of the screen to steer · tap the right: top = fire, bottom = bomb
