I'm doing an idle clicker game about creating a terrarium. Been wanting to make an idle clicker game anyway so this was a great chance.
My original idea was akin to "Army Men" with tiny characters in a massive area but it was just a living room or something.
The theme is more of a guideline. Take it literally or figuratively, or totally disregard it. Scoring high in theme is less important imo than making a game that's fun imo.
