For anyone who may not have understood exactly what to do, or what, why, or how this game works, the in game tutorial is now in, complete and working! (You'll even earn a Steam achievement for completing it!)
The only other real change made in this patch was power-ups all used to appear available to pick-up for 30 seconds exactly. (This is the time they are available for you to collect before they disappear, not how long they last once you collect them).. Now they will vanish a random time that ranges from 25 to 40 seconds after first spawning on the screen. This should prevent the time from being quite so predictable and make things a little more interesting.
