To be honest I mainly added that for debugging.
When playtesting I was unsure if I really lost or if the game had a bug. So first I made all the Geese a different color.
I kept that and changed it to a color transition later on because I figured, if I thought it might have been a bug when I lost, surely Players could assume the same.
And it has the added benefit of teaching the game rather quickly, yes.
Might be a bit on the easier side now but I feel games are hard to balance in such a short time.
Thanks for playing and for the feedback!
