I tried it out, just on keyboard.
game ran smoothly so that is good
i tried the three different control schemes here are my thoughts.
-mouse only is too easy, if you have ever driven go karts at a place where you just hold the pedal down the whole time thats the feeling i got from that, no skill ceiling
-A+D and Space was not too bad to get the hang of
-A+D only, this was pretty difficult, however im not sure that is a bad thing, you might even consider doing a mash up of the control schemes where certain ships have benefits and draw backs, eg: ship goes really fast but has only two inputs (left and right thrust)
i was a little confused on the stats of ships, i tried the grey ship which had low top speed and high turning stats first, then i tried the blue ship that had high top speed and low turning but the blue ship turned way faster than the grey ship, it may have gone a little slower but that wasnt very noticeable, really the speed of any ship i tried felt about the same.
cool concept!
if you could please try out my game, the one im working on currently is this one https://lordricker.itch.io/cadence-blade
