In Dragon Egg!, the heroine carries around a portable dragon which, after many power-ups, becomes a lot less portable to the point where the heroine is portable instead.
This is the author's second publication of Dragon Egg!, this time using the new BizHawk emulator.
Most of the 00:24.69 second improvement comes through a new trick that allows the heroine to simply fly through the auto-scroller level, ignoring the slow paced log.
