I'm not sure. I think it was a combination of me being tired from playing 60 demos and the hard lines of the shader subtly messing my perception of space. I also didn't really like how I put the spear into the pedestal and it started glowing and I looked around to see if something happened, and I couldn't tell, ultimately getting hit in the back by the glowing orb. I wasn't a fan of the glowing orb in general, as I was tired enough to have trouble tracking it, and I didn't feel like it was very fun to hit it with a melee weapon. I missed my spear throw a couple of times as well. I didn't think it was a bad game or anything like that though, I just couldn't get even slightly into it at the time.
