You are %100 right.
They just didn't execute. FRZT did not deliver a competitive product in this space unfortunately.
ANGRY BIRDS, CANDY CRUSH, POKEMON GO... FRZT games are not, as much as I wish other wise.
I made the mistake of thinking their catalogue of games would allow them to grab market share in this space...and I bet on the wrong horse, plain and simple.
Sux for everyone who put money here and lost.
best of luck to everyone in the future
