I really enjoy this game. The fights conditions are preset, but the sheer build diversity allows for different playstyles. My first time through I did a heavy strength build and the synergies were power gained through healing passive, the 2 red 75% damage that procs 3 healing cards, the 1red2orange gain power with each red card used, and a bunch of gain extra energy after doing x passives. This build is very straightforward. Rarely charge, just activate, keep getting new cards and beat the shit out of the opponent.
I got to mid chapter 3 and I decided I wanted to do a low corruption run. This time I did a heavy shield build, with shield slam as my initial damage, swapping over to the skill that causes damage every time you get more shield. My first build was like 15 red, 5 orange, 3 blue, my second build was like a handful of red, a bunch of blue and orange and some yellow draw. Much more deliberate. Set up the defense, then take them down.
The game really shines after you first clear it and decide to do random skills. And that's what the game decided to give me, a whole bunch of random stuff. My first attack skill was unbalancing strike. It does 15 damage and it turns one of the cards in your hand grey. It sucks. Midway though chapter 1 I got the electrify skill that does damage to the opponent each turn when you're bound, and stacks can be increased. So I combined that skill with the one that gives fortitude for each card you discard, and the one that heals when you're being fucked, and it's a totally different playstyle. A lot of draw and multi colored cards. I think next time I'll try and make that null colored skill deck type work. There's a passive that gives you 1 stack of evasion when you play a null card., and there's undoubtedly other stuff in there that'll make it work, too.
My only complaint is how annoying getting endings 1, 2 and 3 is. If rng is with you and you get the purple card on that one specific turn you need it, you're good. If not? Well, you get to load and try again.
