Though his Diamond Trust of London DS game is still missing in action, you can now buy a collection of small experimental games from indie developer Jason Rohrer on DSiWare. Sabarasa Inc., the same studio that ported his Primrose puzzler to the platform, is releasing Alt-Play: Jason Rohrer Anthology today.

The three games included in the collection are his acclaimed life sim Passage, Gravitation ("about mania, melancholia, and the creative process"), and Between ("about consciousness and isolation") -- that last title won the Independent Games Festival's Innovation Award in 2009.

The games are accompanied by artist statements explaining Rohrer's motivations for developing them. You can buy Alt-Play: Jason Rohrer Anthology on DSiWare starting today for just 200 Nintendo Points ($2).
