Sabarasa has released Primrose, the serene puzzler from art game designer and 2009 IGF Innovation award winner Jason Rohrer (Between, Sleep Is Death), for DSiWare today. Previously released for iPhone, Primrose is now available through the Nintendo DSi's download service for just 200 Points ($2).

The simple game features "no time limits, no levels, no arbitrary objectives, and no constraints". Sabarasa explains Primrose's concept:

Just place pairs of tiles on a game grid and attempt to corral groups of tiles with pieces of a different color. Surrounded tiles disappear and surrounding tiles change colors, allowing chain effects to trigger combos for massive points. You can play long matches and try to keep up with increasing levels of difficulty, or just go all out on a huge single-move combo for millions of points.

The Argentinian studio also plans to release a three-game collection of Rohrer's indie titles on DSiWare, titled Alt-Play: Jason Rohrer Anthology, which will include Passage, Gravitation, and Between.

Speaking of DS games designed by Rohrer, whatever happened to Diamond Trust of London, the board game-style strategy title that Majesco was slated to publish this Summer? You would think the company would have shown it off at E3...
