Similar to the XCOM franchise, this is a turn based strategy game. Due to it being an Indie game, it has not been advertised widely. But it is a hidden gem of a game.
The game has a medieval horror setting, but it is not overdone. The in-game animation, art and soundtracks are done perfectly. Especially, the use of only three colors throughout the game (black, white and red), which perfectly conveys the desolate and unforgiving vibe the creators are going for.
The game expects you to lose, you cannot finish the game in a single run. But it rewards your run by progressively unlocking more powers and levels on your daughters (the heros that you control) in your subsequent runs. I recommend the 2nd difficulty mode for getting the true experience( there are two difficulty modes - 1st one heals your daughters for 10% hp at the end of each day, while the other doesn't). In the 2nd difficulty, the damage taken by your daughters are carried forward to the subsequent missions. The only way you can heal is by sacrificing other daughters of a similar or higher level. Even some of your stronger skills in mission require you to sacrifice hp to perform. So you have to weigh the cost/benefits. The monsters are also well designed and the boss fights are epic. You also cant abuse the save option as the game auto-saves and doesn't allow you do do manual saves.
The in-story and lore is also engaging and keeps you hooked. If you are a fan of the turn based strategy genre, definitely give this game a try.
