It was going great at first, but the game is literally fundamentally broken. I get that it's supposed to be roguelike, but the dev promising you can carry over stuff as well as save the game, are all lies. You cannot save, you cannot carry over progress aside from the animations you manually unlocked in the phone gallery. Even then, the 6 special animations you get from accomplishing the stages are deleted as well forcing you to restart. As much as I want to rate this game lowly, it's still beautifully made, and I love the art direction. It has a decent run and gun gameplay that is kind of tedious, but only because of the stupid repetition due to the saves no working.
TLDR; this game could have been great, but its game-breaking bugs really, really drop it down the tier list for me.
