Oh interesting... So I looked in the game and didn't see it. So I actually had to check the game code and it turns out the place where the luster is supposed to be is commented out. haha. Oops.
Unfortunately, I can't just push an update for it at the moment. Void Wisp was made in Gamemaker: Studio 1.4 and I no longer have that installed. Converting the project to 2.3 other than to look at the code is more of an undertaking than I have time for. What I will likely do is download 1.4 again and fix it.
Please let me know if you find any thing else like this!
Thank you!
I'm just glad that I wasn't going nuts, I was going "maybe I need to go through the openings in a certain order..." but nothing else in the game was really like that. Don't feel the need to update solely for my account (it's a fairly linear stage, I figure I'd have probably gotten it within a few attempts) but do know that I did finish up the rest of traveler mode and everything else was accounted for.
Anyways game was neat. I stuck mainly with the premade levels as I work better with definite goals to work towards and thought they were decent bite-sized challenges to take on.
