//BUG: We are currently missing inputs. Fix it by looking at this: https://answers.unity.com/questions/409507/eliminating-input-loss.html
//Bug: When at full speed it is impossible to turn around
//It happens because the velocity delta becomes 0 since no more velocity has to be added
//The fix shouldn't just turn the velocity around, but should also make sure that the proper acceleration is being applied
