Yes, there are people who conduct reviews of other people’s games. There are a lot of them, but some have been closing like crazy mostly because people are getting busy these days. One that is currently active is The Crigence Critique by @Crigence.
He does a good job with giving good criticism and reviews, so I’m sure that once you are ready to submit your game, you can go ahead and do so there (although he only reviews games once a day because he’s busy).
