Muscle mass burns more calories at rest but the effect is very slight. Eating back any calories from exercise will absolutely outweigh any slight change in base total energy expenditure.
Focus first of what you eat, then sustainable exercise, then specific tuning of both.
I remember buying mistmare on cd back in 2003. That thing was a broken mess of a game that crashed constantly, and no returns once you open the seal. Kids these days don’t know what a 1/10 game really is, lol. That game was so bad most of the (short) Wikipedia page on it is about it’s low scores, including a 0/10.
