Here's a game I originally made in 2013! It's called Flying Bill 2. (I can't find the original Flying Bill.) You use the arrow keys to make Bill move. Flying into the brown part of the orange wall to go inside the wall. (Kind of the gimmick of this game) Avoid the fire ball enemies and try an reach the green 'end' orb. It's a really basic game, but was good for me at the time.
The 'coin' sounds are from Nintendo. The thumbnail wasn't in the original, I just created it in the style of this project. The music was different in the original, but I wasn't 100% sure where it came from, so I replaced it with music from Rocket! (New music from a project by jacko1234567 and originally by Vexento on YT)
