Plays like Kula World / Roll Away for Playstation except ball is replaced with astronaut. You jump, collect some green bits and activate switches but there's a twist, when getting close to the ledge you can move to the side of block and flip whole gravity along with the player. Each stage is time limited so keep that in mind also make sure to avoid collecting time capsules as they decrease time. Game have whooping 210 stages so it will definitely take a while to finish. Level design is ok and is divided by difficulty (gets very tough). Main con though, before starting any level you get a quick glimpse at the whole stage however it only lasts a couple of seconds, definitely too short to think about some strategy. Visual side leaves much to be desired and it might feel the game lack some polish. Music is average but could've been worse. Not a bad game, but still I recommend to play aforementioned Playstation classic first to get used to this type of gameplay.
