It's weird to describe this game but the best I can call it is a sandbox platformer.
There is no real goal other than maybe to just get all the achievements.
There's a few interesting concepts and ideas, and it doesn't feel bad to play aside from how much it screams as a Unity game. It can be rather relaxing even if there's no real sense of progression or collection.
It really feels like this should have been a roguelike or something like that given the setting... Until I realize that yes, there's an Early Access follow-up. Maybe I'll take a look one day.
This is a comfy game, totally worth a try.
