Pretty decent start IMO, good to see you learning Unity though it's gonna be nostalgic looking back at your earlier projects.
Anyways some issues I found:
- Player movement was a bit tacky, holding W,A,S,D on it's own made my character run at the default speed however if I strafed, holding down W and D for instance, it felt like my character ran significantly faster.
- Menu glitches out, I opened up the settings then closed the menu, when I reopened it I couldn't do anything except toggle the menu
- Camera is a bit crap, feels inconsistent and hard to control
- Combat needs a bit of tweaking, with it being hard to aim at enemies alongside the movement being a bit inconsistent it just felt very sluggish.
Otherwise, really good prototype
