+_Solving puzzles to build towers_
+
+[Oicana][oicana] is a tower defense game with puzzle aspects submitted to Mini
+jam 71 [on itch][oicana-itch] by [M1nd0fRafa3l][rafael-itch] and
+[@nikl_me][nikl-twitter]. The game was written using the Rust game engine
+[Bevy][bevy].
+
+Colorless puzzle pieces try to reach your base. Your towers have to shoot at
+the pieces to uncover their color. After defeating a piece, it will try to run
+away and you should catch it to upgrade your towers or build new ones.
+
+Following the game jam the tower upgrades where improved and game audio was
+changed to use [Kira][kira-sound] via an
+[experimental bevy plugin][kira-plugin].
