The game was a little too easy...didn't even get half of the upgrades and was still able to finish the game. Up down movement was ok, but going forward and backwards was a serious pain and so painstakingly slow that I just didn't even bothered anymore
I've already finished the game 3 times (reached the max height and got to the ending scene) but I still can't get the badge. I'm I supposed to fully upgrade everything before finishing the game?
