I think the stamina/energy system holds this game back the most, any game that has it for that matter. I think it is, indecisive, selfish, and above all, greedy. All players should have the right to play most if not all game modes as much as they want, especially the core experience. I know you have had this in the game for years now, but it is preventing players from giving you higher ratings, recommendations, play time and that includes you getting less money long-term.

Hit a wall. A well-defined, clear wall. Had fun, thought I'd support the game and go ad-free. Advancing is slow. Yetis and other things make this game not fun. It isn't a skill wall where you can learn to do better. You just die until you don't. Adding more stunlock mechanics isn't fun. Becomes just a painful slog. Would love my money back for the ad-free bit because I can't see myself subjecting myself to that torture anymore.

It's just not a good game. It seems fun at first, but eventually, you will hit a wall and realize that there is no way to get strong enough to get past it. You can upgrade your stats, but it gets expensive quickly, and the upgrades are completely random, so that's useless. You can upgrade your chips/drones, but that needs materials from an expensive gacha system with terrible odds. Even if you wanted to pay to win, the amount it would take to make a difference is ridiculous.
