1.4
is an idle game
gives a ton of currency
no p2w (you cant purchase anything)
Cons:
expensive shop items
eats mobile data more than what it's storage is (hunch that it's running adverts on background or is mining)
slow upgrade progress
you can't buy new characters
if you die at any point of the stage, you start at stage 1 (even if you died at stage 3000 or higher and it takes a long time given that, each stage is around 3 seconds per clear)
