Celestial reversal

in this game you are a robot called "herobot" and you can switch your celestial force of gravity beetwen up and down(down is normal), in this platformer game you must travel beetwen four levels of an evil space facility called "celestia" where you must collect all the 4 purple hexagons to destroy celestia's reign of terror, but be careful, the owners of celestia don't want their hexagons to be taken, so they put enemies that shoot you in there, the bullets are so strong they can kill you in 1 hit(don't expect much from the game, it's very simple)
