Fakemon- Knifefish Sprites

May I please use this for a Game?
If you're wondering what the game is about:
I'm making a huge project
It's a bit like time travel
The main story starts in ancient times (like dinosaur times)
You go on in adventures
The first region you go to is full of dinosaurs and ancient Fakemon and when it's really a massive continent, not all separate regions
I want to make cut scenes and quests and all
Yeah, as the time goes on you will pass away
But then you'll play as one of your kin as the story goes on
And eventually it'll get to the ice age where a majority of the dinosaur fakemon die out (But you get to keep the parchments which has the Fakemon image and info and writing and all so you'll still have info one xtinct Fakemon if you've caught it
Etc, the times go on with new Fakemon and new areas and periods like the stone age and all and eventually to the futuristic age, and the original one region will start splitting into smaller ones
