Hey) There are multiple things I really liked about your game:
First, and I think the obvious, is the music - it rocks. Were you aiming for the Doom style? Because if you asked me I wouldn't tell if it was from Doom or not. For real. It fits in with the overall retro PSX look really well which is the second thing I really liked, kind of reminds me of WipeOut. Having power-ups around the map is also a nice touch - makes you want to run around and explore it. Boss fight, of course. Though at some point I couldn't quite tell if I was damaging it or not. Likely, I found the mortar which solved the problem). Cutscenes really do make the game feel more polished, especially the boss death one. I had my "wow" moment there.
If you asked what IMO there was to improve, I think it would be projectile trajectories, because they kinda felt too short and a unfocused. It made me feel like hoping that the bullets that weren't flying around and actually hitting enemies would deal enough damage so that I don't get killed while spraying the enemy. Maybe also the scale and filtering on the floor texture - it did catch some attention. Having variaty and replayability I think is very important. Multiple objectives or points of interest, like killing enemies and destroying towers, is great. There are already many pilots, but maybe having just two with unique features that would change the gameplay would be awesome and for me personally bring the game to another level. Maybe something like having ability to put frontal shield or even break gates, why not? Or charge something from generators before destroying them? Idk.
I know that there just isn't enough time but maybe next time going full "vertical" (idk, not inglish), as in making one super memorable moment or experience instead of investing in scale, no matter what would be better? wdyt? I don't really know where would you want other people to look at and what was your ideal you were aiming at, but these are just my partly random and unserious thoughts.
Though I'm not sure if you can really consider my feedback about the game feel to be correct enough because my laptop couldn't handle Godot's baggage and the game would begin to stutter a lot when there were enemies on screen. Even worse, audio system would die after 30 seconds or so and won't let listen to the music. So I'm sure I wasn't getting the intended experience. I'm also borderline clueless in art stuff, so I can only give my vibes, sry xD
Btw, I noticed, when you shoot stationary targets and sometimes flying drones, the bullets would ricochet and fly directly upwards into the camera which was a little funny.
Overall, walking around, doing objectives, killing stuff and watching it die Í̵̫̳̓N̷̙̲͍͆́ ̴̺̭͉̍̋̒̈́͠F̸̲͚̦́͑̓͝L̶̙̮̊̿̊͝A̸̭̙͖̺͕̔̈́̕M̵̛͕͇̌͌͘Ë̷͉̦̪́́͑̏̇S̵̻̠̦̱͚̉͑̄̎̓ was fun 👍
