Thanks for the kind words!
In case you missed some control, this game uses 8 keys, WASD ↑ ↓← → , or both joystick thumbsticks to control.
But chances are that you didn't miss anything. If it feels hard to control, to some extent it really is. Characters in this game have exceptionally great motility and are very sensitive to inputs. These features made stunts like this possible. (Normal operation for danmaku battles I guess😂)
Adding more beginner-friendly characters may be the reasonable next step. But for now, my suggestion is to try to be very gentle on the sticks or keyboard. You will get the hang of it soon!
