This version is built in Ren'Py 6.99.14, a major performance update for the engine. The first run of this new version may be slower than normal, as Ren'Py now caches compiled Python expressions as they're reached. Performance will visibly improve starting with the second run. In addition, Ren'Py has added performance options for users on low-end machines and devices running on battery power, accessed by pressing Shift+G at any time.
