Yeah the game was designed around the use of a controller, and keyboard/mouse controls were added last minute, so no tweaks were made for the mouse look, sadly.
And if I would have read down your description I would have seen "Gamepad/Xbox Controller(Recommended For Best Gameplay):"
It was a fun game and I loved the added unlocks based on progress with vehicle skins and baby skins!!! Great feature.
I just appreciate you took the time to play and give feedback! And thanks for giving it a fair shot, especially with the bad mouse camera.
