i think for the outside walls you need either a box collider or rigidbody but for the rigidbody you might have to lock all the axis's, that might fix it but i don't know since i use godot
fun game but you could add somethings to make it better like, make it so the cursor isn't visible when player, make it so the player can't go through obstacles, multiple weapons, and when i played the game and went back to the menu and tried to play it again i could walk around and stuff but couldn't shoot. but all aside its a good game and i meant no offense
