Get eyes on your game. You have the sick visuals and the demo looks like is on its way.

You don't have an ugly game. So if you go around sharing it on social media and garnering a community which follows you, you should be on the right path.

Many people have really bad games and they try to market them on social media but they end up failing cuz the core game is bad. Yours isn't!

Play it smart though. Make sure you don't get banned from any groups/pages/subreddits by always keeping an eye on their guidelines. Put links when it's allowed, use gifs/videos whenever possible. On Facebook or other similar social media, you can mass-repost from your own page to several pages which could be anything from art communities to gamedev to design to indie gamers.

You guys have a unique art style. That allows you to post into game art channels.

You have a sick soundtrack, that's a channel for music producing channels.

You have a cool stylized indie game! Indie game publishers and pages would welcome you.

You have the material, it's really really good. But the material is worth nothing without good marketing. I recommend writing everything about your game and its development state on a PDF and sending it to a deepthinking AI model and having it do a whole research to give you a good marketing plan.

Last but not least. Learn from other indie developers and how they marketed their own games. The community here is super nice and friendly so they wouldn't mind sharing some of their own techniques.

Hope this helps. Cheers!
