To be fair, I had to make some tradeoffs for the performance for the sake of getting the game out and released. In the perfect world, if I had time to optimize, I'm sure it could support wider range of devices. I'll try to pay more attention to that in my future projects, but as long it is just me working on these games on my free time, there's only so much I can do.
Could be your pc too, very hard to say.
