Feedback on Game Impressions and Acquisition (Title, thumbnail, etc.)

Recently, my game’s natural impressions (and as a result new users) have been lowering for some unknown reason and I’m unsure why. I haven’t made any recent changes to the thumbnail or made many changes to the game as I have been working on a major update for the past month (which I finally released). I’m wondering how I can address this issue and what other suggestions you have for improving my game’s acquisition. As of now, my game has a 63.9% new users detail page CTR and a 4.4% New Users Impression CTR. I don’t know what these statistics should look like for a successful game, but to me it doesn’t seem particularly high.

What changes could I make to the existing icon or thumbnails to potentially improve acquisition? Game link is below for thumbnails:

i don’t know either about the ctr but it may be lower because roblox is showing your game for younger or older people
