Jimmy's core abilities are his health, stamina, and fighting prowess. These can be improved through various means:
- Health: Your health bar determines how much damage Jimmy can take. It can be increased by completing certain missions, winning boxing matches, and by kissing girls (especially after completing Art classes). Always keep an eye on your health during combat and use sodas or snacks to replenish it.
- Stamina: Stamina affects how long Jimmy can sprint, swim, or perform certain actions. It's primarily improved by attending Gym classes. Higher stamina allows for longer chases, escapes, and sustained combat.
- Fighting Skills: Jimmy's melee combat abilities, including new combos and grapples, are unlocked by attending Gym classes. Mastering these moves is crucial for dealing with tougher opponents and multiple enemies. Practice your combos in free-roam to get a feel for them.
- Ranged Weapon Skills: While not a 'stat', your proficiency with ranged weapons like the slingshot and spud gun improves with practice. Chemistry classes also unlock new throwable items.
Prioritizing Gym and Art classes early on will significantly boost Jimmy's survivability and combat effectiveness, making the rest of the game much smoother.
