I have collected all of the crystals and nothing heppend :( Also the controls (mainly the mouse) is too sensitive for my taste, my view kept spinning. The column mechanics are a great challenging feature :)
The mouse sensitivity was apparently too high for some. I will definitely add an option for this. 😃
It surprises me that you also had the error with the ending. I'll have to see if I can trigger that too. Did just nothing happen after the last crystal was handed in?
The order shouldn't matter right now. At the moment, a counter simply runs for solved puzzles and then compares this with the number of total puzzles. Hmmm...🤔
Okay, I think I got it. It's probably just the other side of another bug. It should be solved by now. So hopefully the problem will no longer occur in the next version. ^^
