Final polish for the jam deadline!

Unless someone notices a game breaking bug, this is going to be the version that will get judged at Go Godot Jam 4. The submission period ends in less than 8 hours, and at some point I guess I just have to say, it’s done 😅

I polished up some asset issues here and there, and made the drone detect a level change and pause its respawn timer during that. I also gave its homing bullets a bit more steering power.

After running into stability issues with the Windows export, I’ll leave it at just the web version for now. That should work for most (at least in Chromium).
