Even though it's not new, the gravity concept fits this world nice and creates some fun gameplay situations.
My problem with this game was the robot's walking speed. Honestly, it moves so fast that it sometimes takes you a while to hit a button. You just stay next to it, jump and try to not fly too far. That's a bit frustrating.
Also, on the first level, it took me a while to understand that you should touch the exit door without touching the walls (I mean... the sides of the screen where there are no walls, I guess). It is not very intuitive. Would be nice to have some hint for the player on the first level.
Thank you for sharing your game!
