So I've been playing the heck out of this game! I love seeing the progression of the characters as they build muscle. But my biggest problem now, is that they only build muscle while the game is open. I've left the game open for hours on power saver mode and the muscle progression barely moves (using best equipment available to me at the moment). So you have to leave the game running and open on your phone for HOURS to level up the members passed the first four. Starting to get turned off.

Ok, so I've reached the point in the game where you have all of the upgrades that are available. By now, it's impossible to increase sweat drop accumulation or speed up muscle growth in any meaningful way. I'll be honest, it feels like the developer didn't put any thought into this portion of the game. I've reached a point where I cannot upgrade my characters more than once per log in, and that's 8 1/2 hours of waiting. The game is a slog now, and it's lost all of its appeal. Sad :(

We need muscle gain while offline. It's quite upsetting since you can be stuck in a position waiting with the app open as the only way to progress because of the large benefits from muscle tiers for characters. Other than that it's not bad, but with how it is currently i don't see myself playing much longer if they don't add it.
