No problem! I can't rate the game with the joystick because I only have the keyboard at my disposal.
If we talk about the sensitivity of the keys on the keyboard, then in the current version of the game it is redundant. But this drawback is typical only for some cases. I think there are only about 20 or 30% of the total. These are the cases when the trajectory gets a strong change from a small difference in the position of the object. The interval of the required object positions becomes too small to control the keys in these cases.
