Thanks for the feedback, happy you enjoyed it despite some of the flaws.
I didn't realize the way respawning works would cause big issues because I always pushed forward in combat. My son also played in a similar fashion. The importance of playtesting with other people :)
I didn't want to have the weapons simply despawn (ironic since I did it for enemies without batting an eye lash). The plan was for weapons to have a green/red light indicator similar to the triggers to show if the weapon has ammo, but never managed to implement it.
Good call on the texture. I'm terrible at art. I experimented with some noise textures generated inside Godot but because I had scaled meshes all over the place while building the level it looked worse than just a flat color.
I'm pretty happy with how the game turned out despite all the issues but I don't plan doing any more 3D games in the near future :)
