It'd be so great, if any of my choices came to mean anything in the end. Say I gain a neat item or trait; considering the miniscule bundle of events before the game concludes, the odds of both gaining this trait/item, encountering the event where it can come in useful, and succeeding the save, are trivial. The game is too short, with too little player control, for most choices to be meaningful at all... unless I savescum, which is dull. Either allocate more time, or provide additional control over the web of disconnected events, I believe.
Second notice: even with multiple savescums, and two magick shrooms, I hadn't once received the opportunity to cast a spell, or even expand my abilities beyond witchling. In fact, I've not seen a single case in which it could come up, during any of my playthroughs. Yeah, absolutely nothing I do matters.
