Prism for Free!
Many of you enjoyed the browser version, when it appeared in a previous Link Dump Friday, despite some performance issues with the Flash implementation. The download doesn't seem to have those issues, so it's pretty much just a good, fun, wholesome, casual puzzle game that the whole family can enjoy.
Just download the game, and choose "Buy now". The game will be put into your cart with a total cost of $0.00. Don't delay, we are unsure how long this offer will be valid.
Cheers to Zachary for sending this one in! =)
