This is my 2025 Spring Lisp Game Jam submission. It's more like a silly toy rather than a game though. It needs Jwno, which is bundled in the zip archive for your convenience.

How To Run It

Bounce.janet.zip contains everything you need.

The bounce_v3.janet script can work in two ways:

1. Standalone:

Just drag-n-drop bounce_v3.janet onto jwno.exe to launch it, then press Win + Enter when you're bored. Press Win + P to pause it, and Win + Q to quit.

2. Imported as a module:

If you're already using Jwno, you can save bounce_v3.janet alongside your own config, then do these:

(import bounce_v3 :as bounce)
# To start bouncing:
(bounce/start jwno/context)
# To start bouncing with FIBERS:
(bounce/start jwno/context :fiber)
# To poke at it:
(bounce/poke)
# To pause it:
(bounce/toggle-pause)
# And, to stop it:
(bounce/stop)

Moreover, you can right-click on Jwno's system tray icon, and select Launch REPL, to mess with the internal states, and control individual windows.
