Devs responded saying to buy premium. A free game doesn't need to be a cash grab. Free games should be free and not just a ploy to get you to spemd money in game. Have the game not be free to play or ruin the experience for everyone by gatekeeping and adding timers. Try being moral. Ads literally every 20 seconds. Every checkpoint, ad, every level, ad, want special weapons ad, want to buy something other than health at the store, ad. So gross. Must play offline.
