If there is a lot of enemy fire you can´t see your power bar anymore. Perhaps you place it somewhere at the bottom of the screen. Anyway nice game 4/5.
Does the Mission with the Bomber Raid ever end? I kept patrolling the skies after i shot down the bombers and the escort... but the game tells me "Warning leaving Mission Area" on both sides?
Nice game idea. I like the rotating thing as a tactical element. The hexagon based design is quite nice but the unit graphics could use some improvement. 4/5... Well done
