Thank you both for your comments and nice words!
I need to think about the pre-selection of next level, because currently there is no “next level” immediately when you transition to the map (so there will be some problems with animations/forcing selection unexpectedly), but also I want the player to feel that the progression is not strictly linear and they can skip any level and select another opened level (and for that I need not to force the next level selection)
Also, thanks for reporting the bug :)
