I'm sorry but, your username is literally Cummz, you didn't just do this because you had free time, you went out of your way to do it to fuel your hate boner for him. At least be honest about it, I really don't care that much if you hate grummz, but dishonesty is a bad look, especially from a developer. No one makes their username based on someone, then makes a game based on that person, and spends an unhealthy amount of time talking about/engaging with them on social media, without being obsessed.
Make whatever games you want, make a game about destroying Tesla vehicles for all I care. I'm just telling it how I see it.
