A really interesting idea! I had fun trying out different ship builds to beat the initial opponent, unfortunately I couldn't figure out what to do after that. I few a suggestions as well:
- Instead of predetermined (or even re-bindable) keys, a press to assign might be nice so you can choose the key you want to use right then and there (similar to Godot's action key system). Also a confirmation button I think would go a long way as well.
- It would be nice to add a tutorial or some text regarding the Break button as initially I though it meant "Break the ship apart" and not "stop". But its a good feature, I liked being able to stop my momentum even when I was gliding sideways or spinning around
- I would have liked to cancel out of the key / power selection screen and keep the previous bind and power settings (sometimes I clicked on the wrong one or changed my mind)
- The warning overlay confused me at first, it made me think I was going out of bounds, and not warning me of an incoming enemy (so it obliterated me from behind)
But all-in-all especially for a 3D game I think this is really good for a solo dev with (like you said) limited time! If you do a post jam update I'll come and replay it for sure
