Controls and play
WASD tilts the room. A tilt that moves at least one ball counts as one action. Balls stop at walls or each other and collect runes they pass over. The stage clears when a tilt finishes with both balls in sockets. Input that moves neither ball does not count.
Directions work on the keyboard or pad; the pad button also acts as RETURN. SPACE opens confirmation to restart this stage. NO is selected initially. Choose with A/D, confirm with RETURN, or cancel with SPACE. Play pauses during confirmation. CTRL+C returns to BASIC.
Changing gravity makes the balls roll through intermediate positions until they stop. Sounds and motion show the order in which the balls move. Wait for the animation to finish before pressing again.
SOCKETS under GRAVITY counts occupied sockets. MOV counts actions, PAR is the target, and RUNES counts optional runes collected.
Actions and star ratings
Exceeding PAR does not fail the stage; you may still finish. Each board has two optional runes, drawn as circular frames with a cross inside.
| Rating | Requirement |
|---|---|
| 1 star | Clear above PAR, regardless of runes. |
| 2 stars | Clear within PAR without collecting both runes. |
| 3 stars | Clear within PAR and collect both runes. |
PAR is the shortest clear that collects both runes. Every stage also has a shorter route that leaves at least one rune behind. Beyond 255 actions, MOV displays 255+ and the rating is one star.
The 40-stage campaign and retrying
| Stages | Difficulty | PAR range |
|---|---|---|
| 1–8 | Introduction | 4–6 |
| 9–16 | Basics | 7–9 |
| 17–24 | Applied | 10–13 |
| 25–32 | Advanced | 14–17 |
| 33–40 | Final challenges | 19–23 |
F opens stage selection. Choose with WASD or the pad, then press RETURN or the button. All 40 stages are available from the start; you can inspect the selected stage's PAR and every stage's best rating. SPACE from stage selection returns to the title.
After a clear, SPACE retries the same stage and RETURN advances. BEST is your highest rating; NOW is this attempt's rating. A lower-rated clear never reduces BEST. To continue after ending the game, record your password.

Write down PW at the bottom of the title or stage-selection screen. It restores the selected stage and the highest ratings for all 40 stages. It does not save a partially played board; press RETURN after restoring to start that stage afresh.
Codes contain 4–24 letters, excluding spaces; progressing through consecutive three-star clears usually needs 5–6. They use no digits, only these 16 uppercase letters:
ACDEFGHJKMNPQRTW
- Press X at the title or stage-selection screen.
- Enter the code and press RETURN to restore. Separator spaces may be entered or omitted.
- Correct with Backspace (the minus key on real hardware); cancel with X.
You may also select letters with pad directions and add them with the button. Select LOAD and press the button to restore. DEL removes one letter; BACK cancels. Invalid codes and codes from another game are rejected without changing your current progress.
