After ~ 7 hours on this game, i can tell you that even tho there's no "story" (i'm saying no story cause when you start a game you're just thrown into the battle with no context) that's still a good game. Of course it has its flaws, and it can feel repetitive, but it's the kind of game i would come back to when i wanna throw my frustration on the ennemies. There's not a lot of characters or "personalisation" since it's mostly rng (for the items and upgrade) but it's a fun game to play, it kinda reminds me of One piece Pirate Warriors, but without the story + a little bit of MOBAs since you start every run at lvl 1. So yeah, i'd recommend it for those who have some money to spend and feel the satisfaction of killing NPCs over and over, it IS "Endless"

Edit : the feeling of the characters are INSANE, i really hope they will make that game grow in the right direction
