Nice! Yeah, I know that it can be hard to continue development after a jam ends, sometimes they're just quick games for jam purpouses only, but if you're making it better in the future, I'm interested in playing it again :)
Good to know you streamed the creation proccess, wish I've had seen that, can you share your link so I can take a look later?
I've tried pretty much every key in my keyboard (except numbers, F1-F12 and accents)... it must be an issue with the colliding conditions, since the game bugged before and affected the ship behavior, I believe it must have also affected other things, but as you said, really weird that the other collision-dependent functions like showing the icon still worked... anyway, I'll surely play it again.
One way you can try to reproduce this problem is starting a new game, than CTRL+F4 right in the beginning in the spaceship scene, then open it again and use the same slot as before (fyi - the second time was still displaying the slot as "new game" so I think no info was saved in the first time, but maybe some rogue variable caused this)
