Hi thank you for trying the game and for your suggestions!
Regarding the speeding up and rotating with different keys, the controls are fully rebindable (maybe this is not communicated well? Maybe I could change the main menu button to say " Rebind Controls") so you would be able to set it up so that you can rotate with left and right and speed up with up and down.
I'll consider your other suggestions as I try to improve the game balance :). It's my first try and this is has honestly been the hardest thing to do.
Also, unfortunately there's no controller support yet, it's something I may work on adding at some point.
