Shadow Complex part 3: In pursuit of a complete suit
0Ah yes, getting lost for an hour and then sequence-breaking, the true hallmarks of a metroidvania.
This time I'm going to claim plausible deniability - up to this point, the game has always used the blue ! indicator to show where to go next. Well, that apparently wasn't the case anymore, but I followed it anyway... and permanently locked myself out of one item in the game as a result. So that's good design right there.
Upon realizing what I'd gotten myself into and noping the heck out, I eventually found other progression which made it abundantly clear that I had certainly done things out of order. One of the remaining progression items seems almost completely pointless by the time I obtained it, and at this rate I'm wondering if the remaining piece marked on the map is equally pointless, but I've already cleaned up so much of the map that I might as well finish the remainder and see if I can collect it next time.
