Congratulations on a successful jam entry! I see you're using godot! I don't know if this is your first (itch) gamejam, but I would recommend that you figure out how to add a webgl build with godot so other people can play your game in the browser. It's just a big barrier to access your game, and most people don't want to deal with that. In this game jam specifically, the rules say you're allowed to add other platforms (like webgl, or linux, whatever) for up to 48hrs after the deadline. I would really recommend it! You will have an easier time getting ratings and feedback.
Now here is my feedback on your game!
I read from your description that you're going for either a vampire survivors type game with an extra goal (a delivery service) or something more story based. I think either could work. I like the bullet heaven games like vampire survivors personally, but this is something you should decide for yourself.
When I loaded up the game, I first spent a minute or so battling enemies. The controls were intuitive enough, although I definitely kept wanting to reverse my spaceship so I could fire in the direction of the ship spinning around me, and attempt to avoid their bullets without having to drive into them. I think you should add reversing for sure.
I died 2 times. They're very evasive, and it's just very hard to keep shooting them! If you're going for the Vampire Survivors idea, it's okay to just make them real slow, and just spawn them just a little ways outside of the screen all around the player. Also, setting their health really low at the start, and then gradually increasing it throughout the game is good. You could consider little health bars for the enemies, but I don't think it's super necessary.
I then noticed GIANT ARROW indicating my goal (I have been accused of being blind before), and then I drove towards it. But when I did so, enemies stopped appearing in my screen. I was faster, of course, and I was probably being chased, and maybe there is some maximum number of enemy cap thing, and that's why nothing else is spawning? Enemies should definitely still be spawning around me when I'm running away, so you keep running into them in front of you.
Anyway, I picked up the delivery, drove to the new goal, arrived there without seeing an enemy, and then the game showed me an ending screen. I was a little bit letdown. I was expecting there to be another few packages, or more things to do.
I read in the description that there is a boost button. I didn't know at the time of playing, so I never pressed it, but I also don't feel like I needed it. I was going too fast for the enemies already.
Other than that, I like the little planets. Maybe there are a bit too much of them? It'd be cool if they varied in size more.
I've also had a sound guy not show up during a jam a while ago. It sucks. I would recommend that you definitely try to implement some sourced music / sound effects in that case in the future though. I learned this lesson too! There is plenty of free stuff out there on good licenses, even if it's not custom made for the jam. Most of the jam games do that anyway. Having some sound is a huge difference!
That's all for me. Good luck with the rest of your jam!
