Once I understood how to play it was pretty fun to rain lava on my enemies! I wasn't sure how to win the campaign, so I just survived until the angel spawned. At first I had no clue how anyone could possibly beat it, but then I found a strategy where I would just stand above two oceans of lava and water and alternate between those. Man, that thing can take a hit! slowly but surely managed to beat it, and without easy mode! ;) (There were a couple of very close calls though, when I entered melee range and it started kicking my ass)
My criticisms are that it's not entirely clear how to play or what to do at first, and that the angel's health is too high.
I eventually understood that the orange arrows represent supplies (is that right?) but I couldn't for the life of me prevent the assembly from happening!
I liked the art design, the grid based map was actually very cool looking! Made me think of how a 3D Advance Wars would look like.
Gameplay wise I liked the water protection mechanic. And how it "feels" to hit enemies. Also the strategizing with the speed boost once you rain something down.
Sound was nice, loved the soundtrack choice for the ending! And the floating text messages.
The texts in the main menu seemed to be bugged out for me, like some characters were missing, This is from the message near the "final boss" button
Fun game!
