Space shooter game maker

A space shooter is pure arcade: slide your ship, fill the screen with lasers and clear wave after wave of alien ships until the boss arrives. Describe the shooter you want — the ship, the enemies, the power-ups — and the AI agent builds it as a phone game. You play it in the emulator preview, tune it by chatting and download it as an Android APK. The idea above is a retro wave shooter with a boss every fifth wave; change the look and the difficulty before you build.

What your space shooter game will have

From the idea above, the agent builds a complete arcade loop:

• Title screen — the game name over a moving star field, the best score and a Start button.
• Ship control — drag anywhere to move the ship left and right; it fires on its own, so one thumb is enough.
• Enemy waves — rows that sweep side to side, ships that dive in curves and ones that fire back, with each wave a little faster than the last.
• Bosses — a large ship every fifth wave with a health bar and its own attack pattern.
• Power-ups — double shots, a shield that absorbs one hit and a smart bomb that clears the screen.
• Lives and game over — three lives, a short blink of safety after each hit, and a game-over screen with the best score saved on the phone.

Features you can ask for

• An upgrade shop between waves, paid for with coins the enemies drop.
• Several ships to choose from, each with a different speed and weapon.
• Planets as backgrounds that change every few waves.
• A combo meter that rewards quick hits in a row.
• Easy, normal and hard modes with different enemy speeds.
• Screen flash and a short vibration on a boss defeat, with a setting to turn effects off.
• Chiptune music with a mute switch.

Ideas to make it yours

For the common mistakes in arcade games — speed tied to the frame rate, tiny touch targets, no mute button — read how to build a simple game without coding. A shooter has more moving parts than a puzzle; the guide to how long an AI build takes sets realistic expectations for polishing it.

Get it on your phone

1. Press Build this space shooter game and sign in with Google.
2. Play the first five waves in the emulator preview, boss included.
3. Tune it in plain words: "enemies shoot less in wave 1", "bigger power-up icons", "the boss needs more health".
4. Press Download APK and install it on your Android phone; the APK install guide helps if it does not install.
5. For Google Play, build the signed APK and AAB from the same menu; the APK builder page explains the steps.

Play a busy wave on a real phone early. What looks fine in the emulator preview can feel crowded under a thumb, and it is easier to fix spacing before you add more enemies.

Designing waves that feel fair

Good shooters are hard but never cheap. Make enemy shots a bright color that stands out from the background, and slower than the player's lasers. Give every attack a short warning, such as a glow before a boss fires, so the player can react. Keep the ship's hitbox smaller than its picture, which makes narrow escapes feel skillful. After a hit, a moment of blinking safety stops one mistake from costing all three lives. Raise the challenge wave by wave — more enemies, then faster ones, then ones that fire back — rather than all at once. Then hand the phone to a friend: if they reach wave three on their first try and want to beat it on the second, you have built a real arcade game.
