Love the game! Lots of charm, great soundtrack and of monumental importance for the genre.

But it's unstable, bug-ridden and plagued by poor design choices that ultimately make playing the game a very frustrating endeavour, most of the time.

And many achievements are bugged as well.

Nowadays, just get Rebirth (Repentance). If you're curious and want to try this one, there's demos and free browser versions you can find online :D

its worse then rebirth but better than fartnite

Is this game good? I certainly believe so. They didn't remake it in another engine because someone felt sorry for it.
That's the one thing that prevents me from parading in the streets, telling everyone who cares to listen to buy it, though. I consider Rebirth a better experience, especially with the DLCs. Unless you're really frugal, I'd buy Rebirth and it's DLCs first.
That being said, for fans of Rebirth that might want to give the original a try? I'd actually still recommend it. The game feels different, a bit janky, but the fundamentals are still there.
