1.) Acceleration is way too low, max velocity is too high. People shouldn't move like a flying dirigible.
2.) The third person camera is bastardized between two conflicting modes. Critically: W and S (forward and backward) are controlling the character relative to the camera position, and not the character itself.
How it currently works:
A,D,Q and E control movement relative to the character's facing
W and S control movement relative to the camera's facing
None of these keys affect the camera's orientation
a. How it should work (overhead camera / twin stick shooter style):
W,S,A,D,Q and E should all control movement relative to the character's facing
i. W/S go back and forth, A/D strafe, Q/E turn
ii. WSAD turns and moves the character in the direction relative to the screen position
None of these keys should affect the camera's orientation
b. How it should work (chase camera / over the shoulder style):
W,S,A,D,Q and E should all control movement relative to the character's facing
Q and E should cause the camera to move relative to the player
