The rest of Chapter 1, Vision awakening materials, player-summoned Espers and the save transfer to the full game were not reached.Reported ·
Kingy play test: Final Fantasy Resonance demo, Mitra through Grandshelt Castle ↗First-hand play of the public Steam demo (app 4474710, title screen 1.0.0.0; Steam build number not recorded) on the same Windows 11 PC as the October 21 test, keyboard, October 22, 2026, in three sessions. Continues the October 21 save (Chapter 1, party Lv.5, in-game clock 2:29:47), which was started on Normal difficulty. Covers Options and the default keyboard map, field healing, the world-map route from Mitra to Grandshelt, the Royal Capital, with its pickups and battle rewards, Rain's and Lasswell's skill lists and Limit Bursts, Mastery Rank costs for Tronn and Leah up to MR 5, and Grandshelt Castle through its boss, Hell's Rider (party Lv.8, then Lv.9), and the story scenes after it.

Stopped back in the capital after the castle, before the end of Chapter 1. The full game wasn't installed on the test PC, so the save transfer to it was not tested.Reported ·
