Good, good. Game looks incredibly interesting from a design standpoint, if it also plays well, I'm definitely there for a PS3/4/Vita release.
To elaborate, the game's very hard, quite complex, standard "it is a roguelike, for real" warnings all apply. It's not top-down, combat is more like JRPG style lineups of up to 4 characters on each side (ranges matter) and each character has a few set actions they can take on their turn, positioning is very important (and can be changed at cost of a turn).
As you play, your characters get stressed, and quite frequently will go (slightly, at first) mad, causing them to have annoying quirks, for instance one of my dudes turned into a Masochist. Once he stabbed himself instead of attacking, and he would refuse to be a part of full-party heals. Other times they'll just refuse to take their turn, or determine their action on their own.
Every negative has a positive side though, and sometimes they'll fortify their resolve instead of going mad, and then they get a buff, and at least when it happened to mine they often gave the full party a small buff in battle. Managing stress is almost as important as managing HP.
If your characters die it's not a huge deal--the "player" never really dies, if you fail (or succeed, but die, which can happen) you can recruit more heros and use "heirlooms" to improve your basecamp to do stuff like hold more heros, de-stress them, improve their abilities.
The whole game has a very well done grim aesthetic, great art, good sound effects, grim on-the-fly narration, characters all have their own call outs based on their class/personality. Animations are paper-doll, but they're quite well done for that. It's a really well polished experience already, and it's months from release.
Game can be played entirely with the mouse so it should work great on Vita. Haven't bothered with keyboard controls (they exist) or controller controls but I'm sure it'll work out on console. It's all turn-based, at your own pace stuff.
Mobile games are still games. Even if it is F2P, and you NEVER got to spend a single cent or dime on any IAP, but still enjoyed it, wouldn't that be enough? A good game is a good and all that matters is that you enjoy it.
When mobile stops being a bulging teratoma of addiction design F2P, scattershot low-quality games and games that become unplayable 5 months later as they're unprofitable (often all three) it can give me a call. Not interested in basically anything on the platform, it's just not worth the mental stress of looking at the app store anymore. At an ethical level I simply can't support that shit. If it's a good game they're welcome to bring it to PC or console, hopefully without jacking the price up by more than double as seems common.
