I don't know whether to be optimistic or worried. Some aspects look extremely good, some aspects look extremely janky. The most egregious thing for me is the rails in the air. They've put all this effort into making a decent looking world, only for them to have shoved rails in the air. The world doesn't immediately scream "Sonic" to me, but it looks nice, the ancient ruins remind me of SA1. Looks like enemy health bars are back. I'm very torn. I don't think it'll be bad, but this short teaser trailer hasn't really given me hope that they've fully learned their lessons from previous failures.
