Been playing for a week now and I still don't quite understand how the game is going. Can anyone please explain from the start?

I have created a team (Neutral Elf whatever, can't remember) with 3 members. Ok, and so then the quests start. I don't have any problems confronting enemies, but those radial menus when you right-clicking on your selected character is kind of difficult to use and understand. What each attributes does it do? Yet, the game is quite tough. When one of my hero/heroin dies, it says something like the character has collapse/feint but its not yet dead

Like when you're creating a team, you can choose either just 1 alone, 2 or over members/heroes. What happen if you choose just 1 hero? What happen if you choose just 2 members then? And so on.

The map is too difficult to understand and use. The tent for resting, you can set it up for 8 hours. But whats the use of it? What happen if you choose 1 hour? And so on.

However the graphics are great. The playbility and game feature is very detail, though I still don't quite know how the inventory works. The characters are too small to handle, so its kind of tight to choose which enemy to attack and so on.

There are quite plenty of side quests at Homlett town. I don't know which quest should I get it finish first. There is a help guide in the game but it isn't clear as much. There are maybe more problems in the game but I just post these for this mean time.

Thanks in advance.
