Thank you so much for the feedback!
I am currently working on an update fixing the difficulty curve, and I totally agree that the games go on for too long atm, and that the most fun is had close to the VOID.
The idea of multiple diffidulties is really good! I'll have to try it!
Thank you for finding the bug, think I found a fix :)
and Thank you so much for playing! I'm really happy you enjoyed the game :)
