If I'm not mistaken, the developer canceled it and then resumed development shortly after, but indie games usually take a really long time to come out, it's normal. Grindea came out this year and it started development 13 years ago. I've been waiting for Beware and the dev has been working on it since before 2017.

So if we are geting it's probably around 2030, a long wait but more likely than Megaman Legends 3 lol. I'd love a Limited Run edition of this game
