Sort of luck based. Sometimes I only get, with max happiness and skills, 3~4 chances, 2 being almost impossible to score given the distance. Also, your team should be able to contribute more to the score, like 90% of my team's goals were made/assisted by me.
Impressive game. Good to see you took your time to develop the characters and the storyline as well! It kept me enternained for a long time, one of the best RPGs on Kong, no doubt about it. Keep up the good work, I would love to see more games from you!
