Eveningstar is a retro arcade shooter sporting realistic physics and a tactile weapon system: use the orbinging ball of energy to bash, smash and manipulate your surroundings to keep going forward while zapping baddies in ever increasing numbers.
Eveningstar was released by Divine Robot in 2010 and met with great reviews:
“Aesthetically, Eveningstar impresses. Each of the game’s nine levels are set in different elementally-themed locations that draw from unique color palettes. These levels and the enemies that populate them are extremely well drawn, with animation that looks great and feels appropriate for the game’s art direction.”
