And yes, I am well aware that most people who asked for Android version have devices below these requirements, and that not everybody can afford to buy a new and powerful smartphone. And still no, there is no magic in this world to make a game like that to work on every old and budget smartphone out there. Because every device has limits for what graphics it can process due to its hardware.
For instance, you can’t play Witcher 3 on Playstation 1, not even on PS 2 or 3. You’ll need to buy the newest, more powerful, and more expensive Playstation 4 for that. Why? Because only Playstation 4 has hardware powerful enough to process a game like that. It works the same way for all other video games. Games with higher quality graphics require higher quality and more powerful hardware.
If you have an old and budget smartphone, please check Shoujo City 2D instead. It has much simpler graphics, and that’s exactly why it can run on all old and budget devices.
