Thanks!
Considered making a rail shooter ala Panzer Dragoon or Space Harrier, but decided against it (if mostly because I'd actually written one for a game dev competition several weeks ago, but also because I can play both of those games on my Saturn already

).
Decided a sort of racing/time-attack flight game was something that I'd really not seen much of.
I'm pretty happy with Jo Engine so far, was a few hours from me drawing up the idea on a piece of paper and actually getting a moving ship flying over an After Burner style field.

again, I'll post more about it when I'm far enough along to make a dedicated thread with a release
