This was a really polished experience, you even added an options menu! I'm also very impressed with the completed art assets and how the character bounces around in animations. In terms of originality it lacks a bit, essentially being a google dinosaur clone ...but it's a tried and true formula, and I personally had a lot of fun playing it. Another note would be to add a looping and/or parallaxing background to make it feel like you are moving, but that's getting into nitpicking territory.
A great overall submission, well done!
P.S. - thank you for making it playable in browser, its super convenient!
