Sure, I went ahead and played the new and the old version again so that I could see the difference. The updated lighting does help with navigation. I especially like the bullseye being lit; it really emphasizes that there is more to be done there. The new prompt for grabbing the bullet and the roly poly asking about the bullet makes it clearer as well.
Liked the easter egg too. I'm not usually into those types of surprises, but I admit that I jumped a little, lol.
Overall, awesome job. All my experience has been with Unity but I'm about to switch engines to Unreal so really interested in that type of content.
