Here's my game million dollar idea.
I was thinking like you do some kind of genshin impact quest, kill the monsters and in the end there's some chest with the loot, and it has a puzzle.
obviously the puzzles start very easy
like basic adition and shit
and we don't use arabic numbers
but something like old egyptian numbers or sumerian or some shit like that
and the story is a basic jrpg about saving the world
but you need to solve puzzles to save the world
maybe like some archeologist revealing spellls
that are opened by the puzzles
that open other ruin areas
like indiana jhones
You know
Make It COOL
not just another boring math flash crappy game
the trick is that you never tell people they're learning math
