Pelfast (what an odd name!) has made it so you officially have no more excuses for not trying its excellent PSN tower defense game, Comet Crash, by today releasing a demo version of it on the PlayStation Store. In fact, the timing couldn't be better, since if you like what you see play, the game happens to be on sale for $4.99 (down from $9.99) through December 2.

If you're going to get the game (and we couldn't recommend it more, really) and have some Amazon credit or a gift card at the ready, Comet Crash is also going to be available via the online mega-retailer starting later today -- at the $4.99 price, to boot.
