I really enjoyed Into the Breach so I was excited to try this.
I think increasing the number of playable units is an interesting change, although the map feels a bit cramped as a result since one of my units spawned in a corner with an enemy blocking its path more than once.
I believe attacks should say exactly how much damage they deal. Numbers seem to range from 1 to 3 so any difference in damage is significant. Also, since the enemy takes far more actions that the player in most turns it seems like you are forced to take a couple of hits so knowing that would be great.
The controls work fine and they are intuitive, although sometimes it was a bit hard to select which tile to move too. That should never ever fail in a game like this because the player is going to perform this action hundreds if not thousands of times during the course of a playthrough.
I also think you need to make it more clear that enemies can't be pushed off the level to kill them like you would with a normal pitfall.
Besides that I'm intrigued by the XCOM like scan system. I wonder if you want a UFO Defense like early game where you are expected to lose dozens of recruits to the alien menace. That would explain the higher unit count and rather unfair enemy advantage. I honestly prefer that approach where you play as an organization rather than as individual characters because the latter were one of the weakest aspects of Into the Breach in my opinion, but that's just me.
