Thanks for your comment!
First of all all questions answers will be added in the next update of the manual and the typos you can post them here and I will fix it up as soon as I can.
Here we go:
1. You may do one action per activation.
2. Melee range is touching bases.
3. Activation is alternated, so when all units are activated the turn ends. You can place an activation token right next to the activated unit for mark it. (Soon we will make some printable ones!)
4. Attacking is like an action... Yes, actually that is an easier way to explain an activation. You do an move and a action.
5. Adjacent can be read as base-to-base.
6. Morale checks happen each end of a round if the leader or half the warband died. After one of this triggers happen a player must do a morale check each end of turn.
7. I think a small area like 75cm x 75cm with a lot of terrain seems ideal. But you can play on smaller area if the minis can climb it easily. In a near future we will make falling damage rules for games of knocking your minis around.
8. Not yet... But of the inclination seen like gives a nice advantage to the attacker you can give them +2 on the attack roll as a homebrew if both players agree. But also, in a near future we want to release a second playbook with some more conditions, like height, falling damage, difficult terrain and some mission objectives!
