The full game is currently on a experimental "name your price" model, with a minimum price of $1.75 to cover bandwidth and other fees. The game was $22.95 on release.
* 150 stages, with level editor *
* See how the story ends *
* More advanced enemies and bosses *
* No DRM *
* Supporting small developers directly *
* 15% goes to Kiva.org (see below) *
We use a portion of sales for Kiva, a microfinance organization which lends money to the working poor who run their own small businesses in developing nations. So far we've lent over $1250 out to people in 49 countries using the sales of Immortal Defense.

Seen here are Paul Eres (designer, programmer), John Thornton (writer) and Long Dao (composer).
This is not time-limited or a sale. However we may revert to the old model if this one doesn't work out as well as having a fixed price did. I'd like this experiment to prove that this works better than having a set price. Help support the "pay what you want" model for indie games!
