I mean the laggyness kind of goes with the whole theme of old tv game, so its not completely off putting

I'm fairly certain that you did not use 2D lights (as in the custom asset 2D lights) but rather sampled 3D lights and just changed the perspective. That would explain the shadows, the lag and some other interactions.
I feel like turning this project into a full 2D project would make it cool! You got yourself a cool project, it's up to you to make something polished out of it :)
