Need Opinions - yes really - Game Control

So this game, at least this is how it looks today:

I’d like the game to span desktop and mobile, so I’m looking at control. What would you think - is it:

  1. Free movement
  2. Click to move per room, or to attack
  3. Tile based, turn based?

Just looking for opinions really,

Cheers,
