Had a lot of fun last night getting my head around air combat. Staggering missiles is essential and I like the tip of using a standard missile to trigger enemy evasion followed up with the advanced missile - nice!
Do think there might be a few too many ufos, but i won't complain - it's why they call it an invasion tbh!
I think for new users, some explanation of air combat would be good - for example clicking the missile/gun bays toggles them red/green, I think red deactivates or if red fires, but I'm not %100.
Liking it so far and looking forward to seeing how you polish it up over the coming month!
