A few thoughts:
- No fullscreen? It would help a lot.
- I really like the art style. It's got a classic feel but the shadows add a lot of detail somehow. Terrain looks good, trees are a bit out of place though. Overall very aesthetic enginedev look.
- Flight model feels pretty good to me - not too difficult or 'simmy' but not super arcade-esque either. I'm not much of a flight sim player so I can't help much here.
- Space doesn't seem to actually shoot unless I'm just not seeing it / not targeted right or something.
- Enemies are pretty crazy, I couldn't get any of them down but I did dodge a missile once. Again, I'm not a flight gamer so I'm not really your audience here, and I can't say too much on the gameplay.
Overall: Nice little project so far. I'm interested in seeing where this goes.
