Yeah I wouldn't mind to explain some of those things to you the best I can. I'm no expert but I know some things hehe. Is there any other medium where we could talk like discord or twitter?
I have discord, but I have no idea about how it works. I joined Godot channel, but now I cannot see it. It's related to my account actions, but I'm not still sure.
On the other hand, I found a strange behaviour (in my opinion) on your game. On 5th level (maybe it's on everyone), sometimes I react a bit late and touch the inside area of a wall (6x6 with square hole in the center), and the ship does not lose the wing (no explosion), just decrease its speed. I have no capture card, so I cannot show it to you.
I'll tell something about discord when I discover what I have to do.
