I’m about 100 hours in. The interface is obscure in places, the retro graphics do nothing for me, and the randomness of incoming enemy movement can put you in an untenable situation depending on the loadout.
… and I am there for it. The game loop is smooth and it just excels with a simple rule set that gets you thinking creatively. I can do a really smart turn but end it nervously because I left a unit near a corner and maybe ineffective next turn.
