Sorry for the massively delayed response, I have been since working on this again. Hopefully with the new engine you'll find the focus mechanic fixes the high speed issues.
oh, it's so much smoother and more playable now, nice to see you're still working on it! I like the direction this is going in, the ship sprites are great! though, I miss the bulkier UI, it gave the game a unique flavor (I'm weird though so maybe you don't wanna take that to heart haha)
I would appreciate the option to hold to focus, rather than it being a toggle. but that's a classic mechanic and plays great with the patterns on display here! good luck with future development!
