press 'z' to toggle motion-blur on/off. Hold 'space' to keep the purple circle in place.
this is a little something I made today... as the title suggests, this is a sling thingy... press space to stop the purple dot from moving this could be useful for maybe a dodge em up game with the twist that the purple circle dodges the projectiles (like a certain game I know ;) I hope you liked this little demo :D
