If pastels were 'in' when that flash developer made that version it would look very similar too. I have a friend who made a completely different game that looks similar too - https://play.google.com/store/apps/details?id=air.net.paperstreetgames.occulus https://play.google.com/store/apps/details?id=air.net.papers.... I think better evidence is still needed to connect ketchapp and app cow, without that this could just be developers piling onto a simple mechanic + popular aesthetic.
