Before u read this, know that I have no way, shape, or form ever had anything to do with a business. So take these ideas with a grain of salt.
My take on how to get more players involved would be to spread the word on youtube. Make youtube videos (similar to how microsoft does minecraft video/ads), because they are free, and the fanbase you have now is very loyal so they will instantly subscribe, as well as spread the good word of Phobies to everyone they know.
I would also make packs cheaper, not by much maybe 300 coffee less, (The tear packs i feel are fine already). Another idea is make coffee itself cheaper. Or make the coffee rewards per match more than just 5 for winning.
The best idea I have is to sell phobies themselves in the shop, so that way if I really want Primate #9 and it is in the shop I could fork over some coffee for a guaranteed pull, instead of having to gamble on packs. And if I didn’t want him I could just wait until the shop changes and see what other phobies there are. Every week I would do 1 common, 1 uncommon, and 1 rare. That way I am offered a good variety of phobies to buy. But this way packs are not useless bc I can’t get ultra rares in the shop(gambling is still here! Let’s gooooo baby!).
