Cool game! Idk if this was intentional, but I think with a precise position you can get free hits on the machine gun guys while staying outside their vision entirely, and I like that :)
Sound effects work well, music is good but can get a bit repetitive, and I liked the pixel art on the title screen, nice dither for the sky!
Also, the turret cameras kinda reminded me of Metal Gear. Might just be me tho.
