Thanks ! I just fixed it ! :)
The bug is still happening :c I tried to leave the stage with green, but it wouldn't allow me. It took me a little longer to figure out how to get blue from the stage.
An alternative is putting a star on his head and at the end of the level to signify he has to be the one that exits.
Enjoyable game C:
Thanks for feedback ! :)
Actually, the bug was that the colors other than blue got stuck into the wall at the exit and player had to reset the level to continue. It's normal that only blue can leave the stage, but there was indeed a lack of guidance to make it clear... :(
I followed your advice and added some more feedbacks when stage begins and when player tries to leave with the wrong character ! :)
