Approximately Up Time Rewind (P Key)

Time rewind is Approximately Up’s safety net for first-person flight. While in fly mode (R), press P to open the time rewind interface and step backward through recent ship states — useful when you clip a pad, snap a landing leg, or flip an RCS-heavy approach. It is listed in the default Controls menu alongside inventory (I), objectives (O), and blueprints (B).

Rewind is not unlimited god mode. Community events and some challenge rules disable rewind, and it does not replace garage editing (G) when your design — not pilot error — caused the failure. This guide explains when to rewind, when to end flight instead, and how challenge missions treat P.

How to use time rewind

1. Enter fly mode by holding R until physics engage.
2. Fly until something goes wrong (collision, uncontrolled spin, cargo slide).
3. Press P to open time rewind.
4. Scrub or step back to a stable point before the mistake.
5. Resume control and continue the approach.

Rewind captures recent flight history, not garage changes you made hours ago. If you rewired thrusters before launching, fix wiring in G — rewind will not restore old cable layouts from a previous session.

Time rewind versus ending flight (R)

Action	Key	Effect
Time rewind	P (in fly mode)	Rewinds ship state within the current flight timeline
End fly mode	Hold R again	Ends flight and resets scene to pre-flight arrangement

Use P when the ship design is fine but the landing trajectory is wrong — you want another attempt without rebuilding.

Use end flight (R) when loose parts fell off, the frame bent, or you need to patch blocks in garage mode before relaunching.

Many Moon Landing practice sessions alternate: rewind for approach timing, end flight for hull damage.

Event rules: when rewind is banned

Steam community posts describe the No Frame Challenge — build a Moonstep ship without Frame or Window blocks, reach a timed destination, and post screenshots. Official rules stated:

• You cannot use time-rewind during your journey
• All crew must survive to landing
• Stay on the pad 10 seconds until the timer turns green

Similar restrictions may apply to finale content like Fred’s Star. Read mission text and event posts before assuming P is legal. When rewind is banned, rely on Radar, Hover Logic, and co-op spotters (Co-op Guide).

Co-op and rewind etiquette

In four-player online co-op, one player’s rewind can desync others’ perception of the run. Agree crew rules:

• Pilot calls rewind before pressing P on ranked attempts
• Builder stays in garage during timed events — no mid-run edits
• Spotter reads radar/altimeter while pilot focuses on joysticks

For casual demo nights, rewind keeps sessions fun. For challenge submissions, assume rewind is off unless rules explicitly allow it.

Limits and expectations

Time rewind does not:

• Restore cargo power if you forgot to plug in a freezer mid-mission — fix routing in Power and Data Routing
• Fix missing RCS thrusters — end flight and edit in G
• Replace Thrust Calculator math when TWR is too low
• Carry over to the full release differently than demo — treat mechanics as subject to patch notes on Updates

It does help learners practice Controls without fear: reset levers with Mouse 3, rewind with P, rebuild with G.

Suggested practice loop

1. Build minimal hopper in Build Your First Ship
2. Launch (R), intentionally overshoot a pad
3. Press P, rewind, retry landing
4. End flight (R), add hover logic from Hover Logic, relaunch
5. Attempt package mission without rewind to simulate event rules — Missions Walkthrough

Time rewind lets Approximately Up stay chaotic without wasting an evening. Learn P, but do not forget G — the garage still fixes ships rewind cannot save.
