(Below is the original readme included with the first version of the game. The "15 minutes to complete" line is a classic....)

Cat Planet by chuchino
An exploration platformer for Ludum Dare 16

Controls: 
Arrow keys - move
F2 - mute sfx
F3 - mute music
F4 - fullscreen/windowed toggle
Esc - exit
Any other key - flap wings

If you hold up or down then flap your wings, you can control the height/speed.

The mute keys are sort of buggy sometimes but if you press them enough they should work eventually.

No save feature. The game shouldn't take more than 15 minutes to complete though.
