Very good first-person terraforming game. The pace is quite well-controlled until the end; you don't feel like you're stagnating or having to farm for hours to progress. I love how the level design evolves as you advance. However, I found this aspect a bit sloppy at times: the jetpacks allow us to access fairly advanced areas by 'climbing' certain cliffs. Maybe this is intended by the game, but the tops of the cliffs are very crudely physicalized, and there are no items, which suggests that we're not supposed to access them.
