Just to confirm, this one doesn't have Achievements as the Steam version right?

Yeah, this game dooesn't have achievements unfortunately, which is a real pity. :(
I wish the devs would add achievements support someday, I'd surely replay this game from the very start if that'd happen.

Fine by me. I am one of those who generally prefers to just play my games without galaxy straight from the desktop. So no achievements is just a nice excuse for me.

That said, I do wish games would do like how it used to be done or how games like Hollow Knight and Crosscode do it, by having their achievements be ingame.

how does this even make sense though? All their other games do have achievements...

Yeah it's odd. I read the publisher just doesn't want to pay the devs to add them. How true is that I do not know. The Steam version supports them.
