This is addicting!
Make it a mobile app! (Should be simple with Unity)
Create a launching website, add branding (keep it simple)
And ad a daily challenge / and allow users to share it. 80% sure your game will grow fast in MAU

May I ask why? Like Wordle, this game seems perfect for the web browser. Not every game needs to be an app; virtually all mobile browsers allow you to shortcut a website to your phone's dashboard. Wordle demonstrates the general public is still perfectly happy to access a web based game.
I also can't see need to rewrite it in a fully fledged game engine, such as Unity? That seems to me to add a lot of overhead for what is a really simple game.
