+- [ ] Perfect movement
+- [ ] Equipping items (Guns and armor)
+- [ ] Gun aiming and noscope is not the same position
+- [ ] Controls being bindable
+- [ ] Gun moving out of the way on a collision
+- [ ] Gun moving when walking, when running, aimed in.
+- [ ] Visual effects for camera

 - [ ] Fix: Make gun have more priority in rendering. So it doesn't clip through walls
 - [ ] Feature: Give a collider to the gun and when it collides with something make it move out of the way.
 - [ ] Feature: Add bullet holes
 - [ ] Fix: No Sprinting while aiming
 - [ ] Fix: Movement is clunky and very linear. Add some sort of Lerping for acceleration vectors.
-- [ ] Feature: Muzzle flashes for shots
+- [x] Feature: Muzzle flashes for shots

 - [x] Feature: Add smooth camera movement to camera on crouch. Right now it's too fast and looks arcade af.
 ~~- [ ] Feature: Add jump effect to camera~~
 - [ ] Feature: Add Stamina (with bar?)
 - [ ] Feature: Subtle Headbob, FOV change on movement (Distinguish between sprinting and walking).
-- [ ] Feature: Basic ESC UI, FPS counter, stamina bar
