I have a couple of tips for getting a lot of ratings.
If it fits your game, make sure you have a vibrant thumbnail. Seeing as my game has a colorful artstyle, I can make a thumbnail that really sticks out.
Give your game a name that fits with the game, but leaves people wondering what it might mean, I noticed that people click on it.
Instead of working to the last minute before the deadline, I worked during the night so I could release my game early, this way you get a head start since your game will show up in a small group of other games, instead of being compared to 6000 games, my game was being compared to 500. That combined with a good thumbnail and you get really far.
Don't make the game too long, since my game is pretty difficult people may lose interest if it's too long. People want to play other games so keep it short or else people might leave without rating.
Hope this helps! I will definitely check out and rate your game!
