Pretty good game, I must say. I completed this in a single hour. Honestly, I think Pico Sim date 3 is better, but this one's not bad. There does not seem to be a cap for intelligence, strength, and charm. I would recommend capping these 3 at around 350-ish. As for the actual random fights, they were quite easy, just make sure you hang out with all types (nerds, jocks, gangsters, emos) and learn all their moves. These battles can be won easily if you have high enough stats (for me, I did 300+ each). Also note that certain types are weak against others (if you fight a "cool" guy, using jock moves on him deals the most damage)
"Cool" Guy - use Jock moves on him
"Jock" Guy - use Smart moves on him
"Nerd" Guy - use Cool moves on him
"Emo" Guy - use Emo moves on him (this one's actually quite surprising, I thought it would give the least damage, but I digress)
I liked the random chance options with the workplace. Overall great game!
