Starter recipe: a learning template written by Vibe1Up from the game's public description. It has not been reproduced in a fresh AI-builder session. It is not the creator's official prompt. Are you the creator? Share yours and we'll show it with the Creator's prompt badge.
A prompt you can paste into an AI coding tool to build a game like this one. Based on: the listing and the live game page (checked 2026-10-14).

Build a small, playable browser game inspired by "EraPlane" (Shooter).
Concept: Top-down air combat across eight eras. Start in a 1915 biplane, climb to a jet in one life. Free, no account.
Tech: use plain HTML, CSS and JavaScript (or a lightweight engine you know); keep it to a single page that loads instantly with no login or install.
Controls (as seen on the original's screen): mouse to aim or look, click to shoot/attack, Shift to sprint/dash. Show them on a short how-to-play screen.
Players: single-player.
Core loop: include a visible score, an optional local high-score table.
Steps: 1) get the core mechanic playable with placeholder shapes, 2) add win/lose conditions and restart, 3) polish feel, visuals and sound, 4) add your own twist (setting, character or one new rule).
Make it your own: don't copy the original's name, art, text or code.
Affiliate link: we may earn a commission if you sign up or pay through this link, at no extra cost to you. A recommendation is not proof that this recipe has been reproduced in that tool.
EraPlane was made with the Unknown engine engine, according to its listing. The AI tool or model is not stated in the source.
How do you control EraPlane?
The game's own page mentions mouse clicks. We detected this from the live page text; the creator hasn't confirmed a controls list.
Where can I play EraPlane?
Free in your web browser on foremangames.itch.io, the creator's own site. Vibe1Up links to it and doesn't host the game.
Is the prompt for EraPlane official?
No. The prompt on this page is a Starter recipe: our own reconstruction from the game's public listing and live page, not the creator's official prompt. If you made this game, you can share your real prompt at vibe1up.com/prompts/ and we'll show it with the Creator's prompt badge.
