Yeah, I had the same criticisms. They are somewhat allayed when you get out of the city and into the forest areas. It gets less cluttered in the forest, but the limited color palate still made me confuse shiny objects for drops/pickups sometimes.
And just to warn you, eventually you will get out of the forest and back in the city again. Luckily, you’ll be more enamored with the gameplay by then, if you’re like me, and won’t mind it as much.
