Re: 棄てられた島-セラの孤島脱出冒険譚-
An RPG that focuses almost exclusively on petrification/ASFR is pretty rare, but this particular game was simply underwhelming. Scenes are only available from bosses, and triggered by a one-time choice when you get their health to 50% or less. Depending on your choice, you either continue the fight or go straight into game over.
The game isn't that complex from a technical aspect either. It's all about getting your TP up to use the right healing spells when needed, and spending any extra on damage. As long as keep your TP high, and aren't woefully underlevelled, you'll never die in battle.
