I have been seeing you promote a lot recently. However, some significant issues are here.

Issues here:

• Shoot the slimes has a cover image  that does not relate to the game
• The url is misspelled as collect the starts
• Beginning is spelt wrong in the video
• The video opening is not that good.
  • It starts with Unity for ~5s
  • It does not show the primary mechanic until 18s
  • This means that marketing with this video on socials won't work
• No screenshots
• Descriptions are too short
  • This post is longer than both of your descriptions
• Number 1: Add a web version
  • Gets you around most of the issues

I get that you're trying to beat your siblings thoughts.  This shouldn't be the primary reason to download, it should be game related.

Secondly, views to downloads seem to be low. My assets  have ~3% view to downloads.

My game had: 421 views, 70 plays, but just 6 downloads, since 7/23, which is when I made a  downloadable version .  

I did the same thing, making a bet that I would get 67 views at the beginning of the year. I failed.  But now I'm at 9,700 views .

Focus on generally improving the page, and the game, and the views/downloads will follow.
