You forgot to post a link to your game’s page. This will make it easier for users to find it.

Congratulation for the Early Access launch, hope it all goes well :)

Here's some unprofessional personal opinion!

For the page:

I appreciate the effort of making a trailer and screenshots, which is very nice! The banner is quite good as well. You can also consider putting some screenshots in between your text as well to make the text more lively (I think?). For the download section, more consistent naming for your downloadable files will be better. Like I'm a Windows user, I'm not sure whether to click Build.zip or Build_EA.zip . Also try point-forming the features of your game, so readers can know what your game is about before their extremely short attention span runs out :P

For the game:

The game kinda.. freezes? I can't click anything and there's no response to any input I made. Though the music works fine. Do let me know if you found out why :P

For marketing:

Social media is a good way to promote, as I haven't seen you have connected to any social media accounts yet. You can post screenshots or videos there with some hastags, people may click in and see your posts. If they are interested, they will probably have a look at your profile! Try Twitter and Instagram.
