There are instructions on the games' description that explains what the buttons do exactly. I admit that they should've been included in the game itself, but I unfortunately ran out of time. If I could've worked with the game longer, I would've also added unique names for coins and fixed the counter going below zero. Next time I'll start my game a bit earlier, so I can polish it for longer.
You're right about the font. I had time to pick a better one, but I just picked it because it was CC0 lol
