Dodge the pipes, and don't touch the ground either. Kirby falls automatically so you must press up arrow in order to go up. If you want to fall faster, press the down arrow. If you press space, it will pause the game. Every time you go 25 meters, it speeds up until it gets a certain speed.
I didn't want it to be a exact copy of Flappy Bird so I made Kirby a little floaty like he was supposed to be. Just so you know, this is a Demo so I haven't put all my ideas in it and it may have some bugs but I did test run it. I plan on putting music in it. If you find any bugs, tell me in the comments so I can fix in the new version.
