gameplaywise this does not beat "Fight'N'Rage which is also available on GOG. The graphics and music are awesome. Combos are fun, but u got to unlock them and it it is not as intuitive. The bosses can be really hard. You have to learn their patterns in Order to beat them. That being said the checkpoints before boss fights are kinda annoying. You have to walk a little to the boss room again and the damn dialogue starts again. The Game is awesome and fun especially due to the presentation. But if you just care about the actual gameplay I'd recommend Fight'N'Rage over this one here.
I bought this not reading the description or watching Videos on YT. The low price, some screenshots and the positive review score were enough for me to buy this. And I am not disappointed. I expected a "normal" indie fps. But this game actually feels like (I am really sorry for this...) Soulsborne with Guns. Maybe like remnant from the ashes? (haven't played that one yet.) It is fast and skill based. It runs smooth and I didn't notice any bugs yet except some graphical flaws when you are in the menus. Be warned though. I do not think this kinda game is for anyone. Buy it if you want to support the devs to finish the game. I really wanna see what the final product is like. Keep in mind that it is Early Access.
