88 €?

Hi! Ok, so I get it has like, tower defense elements, survival crafting, combat, etc. etc.. BUT, do these all take place at the same time? I.e. is this a typical survival crafting "RPG" type of game? Or does it take place in levels or stages, like Stage 1 is build a base, then that part ends and you're onto a new 'stage'? Or is all the gameplay combined in a huge open world, err, moon. Any help would be appreciated, thanks!...

and it isn't even in early access. Such a high price tag for an empty game looks like a scam.
