Notes:
(1)
No background file for this one, as it draws what it needs using code.

I noticed on level 4, if you don’t touch anything on your controller, you will
fall through the bottom of the stage and the game will crash. This is because
pull of gravity gets stronger with each loop, and if you fall for too long then
it is possible to end up with a Y position that is out of bounds.
Game Instructions:
You control Icarus. Gravity will always pull you down, and if you move left
or right (using the d-pad) then some inertia will kick on so you will
continue to list left or right after you let go. If you hold down the “A”
button, Icarus will flap his wings start to pull you upward.
The objective of the game is to master the controls and collect the blue
coins without touching the walls. You only have one life, so if you hit a
wawll it is game over.
You can also design your own level! If you use Family Basic’s background
tool, you can draw the level using the “F0” tile for walls and the “G7” tile
for coins. After doing this, edit line 30 in the listing so that “G(0)” gets
set to the number of coins in your stage rather than zero. Now when you run
the program, it will have you play your original round before advancing to
the first level.
Cheats:
The level data is found on lines 510 through 550. If you want to try a later
level, you can swap those lines around so that the level you want to play
comes first in the list.
