A downloadable game
Set the angle and velocity, compensate for terrain and wind. Simple.
A fun little physics toy for a single player, best enjoyed against a human opponent
I tried unsuccessfully to make this game in the early 1990s. A lack of physics knowledge and the challenge of drawing the trajectories at a reasonable speed defeated me. Over two decades later, and inspired by the ZX Spectrum nostalgia of the recent Black Mirror special Bandersnatch, I decided to have another crack at it. I used Wikipedia to model the physics, and with some design choices I got the trajectory traces and collision detection fast enough to make the game viable.

I started this Sinclair BASIC game around 25 years ago using a Spectrum +2 and a C15 cassette tape. I wrote the bulk of it during a couple of weeks of late nights in February 2019, using Fuse for macOS in 48K mode with a Recreated ZX Spectrum bluetooth keyboard for the authentic keyword typing experience. The tool listbasic from fuse-utils was invaluable for allowing code review on a decent resolution screen.
