>Make it a mobile app!

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.

Retention and engagement is much higher in mobile apps. Allowing you to get a much higher ARPU. Especially for games with In App Purchases.

Why does it need to be monetised?

I was under the impression the game was built with a game engine thus allowing easy rollout to mobile without having to rewrite.
