Thanks for criticism! Yes, friends who tried did complain about the acceleration and range, same for AI, but as I started a week late, I didn't have time to do proper AI. Fortunately, I quite liked working on this, and I might rework some stuff for a full game. Regarding the audio issue, I have a theory that maybe you have multiple outputs and the game is trying to output to somewhere different. I haven't changed any of the output preference, so it defaults to the system default, possibly in a future update I will give the option to output to preferred audio device.
