# OMA-LANDER

A faithful Lunar Lander arcade recreation for Omarchy Linux, inspired by the 1979 Atari vector cabinet. Built with Love2D — pure Lua, vector line graphics, procedural terrain, procedurally generated audio.

The lander itself is drawn as an Apollo Lunar Module silhouette: wide octagonal descent stage, angular ascent-stage cabin, splayed A-frame legs with saucer foot pads and surface probes, descent engine bell, docking tunnel, rendezvous radar, and triangular cockpit windows.

## Install

```bash
curl -sL https://git.no-signal.uk/nosignal/oma-lander/raw/branch/master/install.sh | bash
```

## Uninstall

```bash
oma-lander-uninstall
```

## Controls

| Input | Action |
|-------|--------|
| **Up / W** | Thrust (main engine) |
| **Left / A** | Rotate counter-clockwise |
| **Right / D** | Rotate clockwise |
| **Space** | Abort burn (auto-level, kills horizontal speed, heavy fuel cost) |
| **Enter** | Confirm / advance menus |
| **Escape** | Back / quit |

## Gameplay

Select a mission difficulty, then pilot the LM down through procedurally-generated lunar terrain to a marked landing pad. The camera tracks you and zooms in as you descend — altitude, horizontal and vertical speed, fuel, score and time are on the HUD.

### Mission difficulties

| Mission | Gravity | Fuel | Notes |
|---|---|---|---|
| **CADET** | 8 | 1000 | Training — low gravity, extra fuel |
| **PILOT** | 12 | 750  | Standard mission |
| **COMMANDER** | 16 | 600 | Heavier pull, less fuel |
| **ASTRONAUT** | 22 | 500 | Elite — extreme gravity |

### Landing pads

Three pads are placed on each generated map, each with a score multiplier. Narrower pads pay more:

| Label | Width | Multiplier |
|---|---|---|
| 2X | widest | × 2 |
| 3X | medium | × 3 |
| 5X | narrowest | × 5 |

### Landing results

Your touchdown is graded by vertical speed, horizontal speed and tilt at contact:

| Result | Required | Score | Fuel bonus |
|---|---|---|---|
| **A PERFECT LANDING** | on pad, v<8, h<15, tilt<5° | 50 × mult | +50 |
| **GOOD LANDING** | on pad, v<15, h<30, tilt<15° | 25 × mult | +25 |
| **ROUGH LANDING** | on pad, v<25, h<45, tilt<25° | 10 × mult | — |
| **YOU MISSED THE LANDING AREA** | off pad, survivable | 5 | — |
| **CRAFT DESTROYED** | else | 0 | — |

Run out of fuel and the mission ends. Top-10 high scores are saved locally; enter three initials on a new high score.
