I'll be honest I think this game suffered for me from the way people are talking about it. I think people are very hungry for this style of design where the game really doesn't tell you a whole lot upfront, and whenever people start saying "don't spoil yourself just play it" about a game, it will tend to create hype all on its own. So I ended up playing this game, seeing the things it was doing, going 'neat!', and wondering when the Cool Thing that people were so hyped about was going to show up. I think what was going on there is I'm jaded, heh.
Ultimately I'm not going to finish the game because while it kind of presents itself initially as an exploration- and puzzle-driven game, almost a pure adventure game, for some sections of it it just decides arbitrarily to turn into a frustrating precision platformer with very punishing checkpointing... and I just am not going to invest time into that.
(slightly spoilery further thoughts)
I think your experience of this game probably varies a lot depending on your level of comfort with this style of play or your experience with games in this vein... Take the flute for example; I figured out how to warp with it pretty quickly, and went "neat!" at it. I've seen this style of affordance before. Even the puzzles I only kind of gleaned they were there I kind of immediately developed suspicions about what might be there. I think this game is probably already kind of 20% ruined for you if you've played Fez.
But like, someone might have picked up the flute and not realized it can do more for ages. Or they might miss the flute entirely (is it part of the critical path?). Or they might be shown the warp spell by a friend and go "ooh".
Also incidentally does anyone know how to get past the (loose) ostrich. Not because I need help, I did get past it and I just have no idea what I did to make it go away. Bug, maybe?
