+_Jumpy Items: Swords, Crates, Grenades, & Mines_
+
+[Jumpy] ([GitHub][Jumpy], [Discord][jumpy_discord], [Twitter][jumpy_twitter]) by
+[Spicy Lobster][spicy_lobster] is a pixel-style, tactical 2D shooter with a fishy
+theme.
+
+In the last month, Jumpy migrated from a client-server networking model to a P2P
+Rollback model using [GGRS]. This was to address shortcommings with the server
+model that had been implemented, and to take advantage of the excellent user
+user experience that rollback networking can offer.
+
+The rollback model did come with the new requirement to run up to 8 simulation
+frames per 16ms screen refresh, though, and unfortunatley the JavaScript
+bindings used to implement the game items were not performant enough to keep up.
+For now, scripting has been temporarily disabled.
+
+This sparked a quick migration of the TypeScript files to Rust, and also
+[discussion][jumpy_wasm_discussion] about future possibilities for using WASM to
+get beter determinism and rollback performance, along with lower-overhead WASM
+scripts.
+
+With promising ideas for future improvements, the rest of the month was spent
+focusing on getting the initial items completed, with Grenades, Swords, Crates,
+and Mines all landing recently.
+
+With just one more item planned and minimal clean up work, an MVP release is
+just around the corner!
