Got a time of 08:07. This is a fun game! How the heck in the story this is a one-man job I'll never know, but I managed to defeat that thing with one turret down still. Neat! The retro 3d style is super nice, with smooth gameplay, good sound, and voice over too! I especially like the rocket control that is slow enough to be controllable yet requires some precision to navigate inside the asteroid. This reminds me of a turret section from an old dogfight game that I really love. Thanks for that nostalgia trip.
For some criticism I'd say using the middle mouse button to switch turrets is nice for sure, but makes someone like me who uses mouse with smooth wheels way harder to play. I think using button presses would be a better choice and would allow more precise gameplay. The enemy also hits quite hard too, and would take away almost half a turret's health in seconds. It's quite harsh when I am focusing on dealing with a single side and getting the other side destroyed immediately.
But anyway, this is a very nicely built and polished game! Well done!
