Zach Kehs’ Koya Rift is on sale at $1.99 this week.
The procedurally generated shooter is available both on Desura and as a direct DRM-free download at the lower price (the game is normally on sale at $7.99).
IndieGameReviewer.com has perhaps the most detailed review of the game which praises the games appearance but recounts of repeated tunnel section and enemy graphics.
Probably best to stay away if flashes aren’t for you!
Just letting you guys know, I made a reddit thread about this game (not expecting much), but I got a HUGE amount of feedback! See it here: http://www.reddit.com/r/gaming/comments/pc0jt/i_decided_to_put_my_game_on_sale_for_75_off_199/
