Regarding turns; sorry, that was bad player-onboarding on my part. 😅 You should be able to move all of your pieces across one turn so long as they have abilities left to cast (i.e., each having one use of Move, Leap, and Attack.)
The ability to attack your own guys wasn't unintentional, but I might perhaps prevent damaging abilities (or add some sort of "Are you sure?") from targeting allied units in future versions. OvercastHawk mentioned that it could potentially open up room for creative shenanigans like clearing spaces once a unit's already moved, though, so who knows. But either way, will definitely highlight the scenario in the next version.
