Hey Johan, thanks for playing and sorry you couldn't reach the end!
The cross is a false friend - there's one cross which is "full" with a dot in the middle and the other cross (which you screenshotted) where the lines do not touch each other in the middle.
It's the trickiest one of the bunch and has fooled a couple of people so far. Sorry it threw you off too much, hope you still enjoyed the experience!
