Challenging but fair. Although sometimes I get mixed up with the controls or the controls are weird. I made it to the 3rd planet. I wonder if the threats mentioned in the level select are just for fun or do they do anything? Anyways, fun game.
I toyed around with the controls for a bit. When you're on the bottom, sometimes up seems like down, but I settled on consistency overall. Caveat of a little grace if you press the wrong on button on the edge! The threats are fun just for now. Anyway, Thanks for the review!
