Hey, congrats on your first game, you have my deepest respect for achieving this at your age. When I was 14, I only made games that were 10% finished and then lost interest.
Since you are making a similar game to mine (Football Manager) feel free to let me know if you have any questions or need any assistance :)
And good luck with your game!
p.s. just one word of advice, if you want to make the game bigger and reach a wider audience, you might consider changing the club names and have an editor for them. Otherwise, it can lead to legal trouble (though it might have been a lot of work entering all those names!)
