Very cool to see an update! I think I've collected all the effects, images, and mini-games, but I think the ending may be bugged. Are the puzzle pieces supposed to connect together?
Yes, all the pieces are supposed to come together and the final door will appear. I was testing and the bug didn't appear, instead a different bug appeared in the minigames that I hadn't seen before. I'll try to fix it as soon as I can, but regarding the final door bug, I still don't know why it happens. Try opening a new game and getting the effects again to see if that fixes it. If it still happens, confirm for me. Maybe it has to do with the order in which they are obtained or another factor. Any information would be helpful. I'll try to fix what I can.
