It's free for PS+ right now and it's a charming and fun game. It's short, so it'll be a good balance to all the huge games, and it is a simple concept. You control a little robot that lands on an island and has to propagate a giant plant up 2km to get back to the spaceship. You do this by hopping, then rocket packing, and then gliding around.
The graphics look like if PS1 era graphics were high res and colorful, super good looking there. It's a lot of fun to hop around and grow the plant out to remote floatin islands and explore. Plus the achievements are easy and fun.
The game also does give a dizzying sense of height that few games have provided.
It's fun! It's cute!
