it's a sad story but true.
When you making game in order to know whether your game is fun or not you've already finish making that game. I'm feel like I've to start over from the beginning again.
I've decide to change the orientation from portrait to landscape so that player can see longer and can plan their decision.
I've learn to know that decision making is the core fun of every game. The old game not giving player enough decision choice for each situation, player only need to collect the resource need to continue.
In this new one player can shoot,reload,hide,run,change weapon,use item, etc. This bring a lot more choice for player to cope with trouble. It's also making a reward more rewarding.
