Oh nice one, clever idea! Managing strength and fatigue is a real challenge. The first two are finger-in-the-nose easy, but by the third one, you’re not feeling so confident anymore!
Thank you for noticing. That was actually a part of the game design where the first 2 are easy (because you’re overpowered), where the third is still beatable but can be difficult if you don’t go to the gym. Fun fact, you cannot lose against the first opponent! :D
