This is one good-looking game! The graphics are definitely professional quality, and the two environments (caves and tech lab) have a very different mood to them. It's really outstanding, especially for a game jam project. I also really liked the look of the synthosaur. My GPU wasn't super happy to have to render all of this, but that's to be expected from an early prototype like this.
I'm a little torn about the platforming. The horny metroidvania mechanics work, I think, but the running and jumping felt a little clunky. There's a lot of weight to the synthosaur, which is good if you're going for a real sense of physicality, but might not be the best choice for precision platforming. Something to tinker with, perhaps.
All in all, good job!
