So it was some kind of bug i guess.
After the third puzzle, I saw an Ending screen, when I clicked the screen again the game continued. So I did saw the ending screen twice
Oh wow.
So 1) A very big GG for making it this far... Because I didn't haha. When I finished the level design I was so late in the schedule and I was pretty sure it was practically undoable. Thanks again, I'm really happy to hear someone made it to the end.
And 2) I'm really not surprised of the bug you mention because we implemented this ending screen at the very last minute (rookie mistake) like just before uploading the game.
But then again thanks a lot. Knowing that someone played our game that long and could had some fun on it means a lot to me.
