The feature that pauses the game when an ability procs is an amazing teaching tool. Made learning the game a cinch.
I really respect the decision to design an auto battler where death, damage, and even summons persists from combat, however, I am concerned about this design. There's a reason why no other games have done this, and it's because it makes the game into a real feast or famine situation.
Right now, it feels like the only way to win is to abuse the 5th cell to make one unkillable unit, and scale from there. When I did that, the game felt pretty trivial. When I wasn't doing that, I was having to rebuild my comp nearly from scratch every round. Playing the game "fairly" just felt like re-doing round 1 over and over again because I couldn't get any of my units to stick between rounds.
Another consequence is many of the relics feel useless. Why would I ever spend money to give an on death effect to a unit if it can only ever happen 1 time? The only time I'd consider buying this is if my board is full, at which point I probably was already winning anyway. The relic that gives a unit taunt is useful, but getting the pair feels actively bad because you'd only ever want to put it on the unit which you're scaling in the center cell. But that's also bad because that's the unit you want to draw damage away from, so it's kind of a cursed problem.
Game is very cool and promising, but it really needs some more systems to complement allies not reviving between rounds.
