Glider 4.0 Unofficial Web Edition is a browser port of John Calhoun's 1991 Macintosh game Glider 4.0, in which you fly a paper glider through the rooms of a house. dbohdan ported the released THINK Pascal source to TypeScript and reimplemented enough of the Macintosh Toolbox to run it, so it is a source port rather than an emulator. It includes the houses, art and sounds from the Glider 4.05 release, plus the Room Editor for building your own houses.

How to play

Fly with the left and right arrow keys, use the down arrow for a battery boost and the up arrow to fire a rubber band. Tab pauses.
On a phone or tablet the game starts with on-screen buttons; menus work by tapping and holding a menu title, then dragging to an item.
Gamepad and Virtual Gamepad modes are under Options, then Controls.
Quit the game to reach the desktop, where the Room Editor lives.

What you need

Nothing: no Mac ROM or system software. Saved games, houses and preferences stay in your browser's storage, and the desktop's File menu imports and exports them.

Good to know

It starts in a mode that imitates a 16-color Mac II. Options switch to a black-and-white Mac Plus or Mac II, or to the look of Glider for Windows, and add screen filters.
The port keeps most of the original's bugs so that it plays the same way.
The README says the port was directed by a person and written by Claude Opus 5.5, and tested against the original running in an emulator. Source: GitHub.
