What is Reddit's opinion of Resolution changer Power Menu?

From 3.5 billion Reddit comments

I believe the vine should be focusable if you mess with the DPI of your device through a tool like Resolution Changer Power Menu. I managed to focus it once when I was still figuring it out for the minecart game, but I didn't click the "Clear", and afterwards, as I finally figured the resolutions for minecart, I never got to focus the vine again.

That "100x400/600 at 220-270dpi" is extremely vague - on many phones (well, at least on mine) it will leave you unable to even launch the game. Especially messing up DPI against screen resolution totally screws up the Android interface.

NOMone Resolution Changer doesn't work with Xiaomi phones. Resolution changer Power Menu does - use whatever works for you.

If you use RCPM, Set to 'Apply default on power off', don't set 'reapply setting at power on' so you can fix things by rebooting your phone if you mess up too badly. Nevertheless, you WILL need Root, and give the app superuser privileges. (blessed be the Chinese, for Xiaomi comes pre-rooted...)

Move both MLP and the res changer app icons to upper left corner of the Android desktop. The right column will become unavailable, others may or may not. (both may be on separate desktops, switching by swiping still works). The interface WILL be screwed up, probably including on-screen buttons, AND the Res Changer UI. While Reboot resets it, some after-effects may stay if you just restore the defaults through Res Changer. (in my case, I'm getting four tiny battery indicators in the status bar instead of one...)

Also, force close MLP before playing with the new resolution. Use one of hundreds memory-cleanup programs, if your system doesn't provide one. (on MIUI: menu, long press the MLP icon, "(X)".) MLP will probably crash/hang if you change resolution while it's running in the background. Restart it once the new res is applied.

The actual tip can be split into two (that can be combined):

performance upgrade:

Reduce the native width, height and DPI all by the same factor. Halving them all should be aplenty already. (RCPM provides a handy "calculate" feature. Halve one of the numbers, the rest will be adapted to match). This removes a burden from your GPU while leaving the rest alone. It shouldn't even screw up the UI too badly. The game will run smoother but will still look similar, if less sharp.

If you want to combine the two tips, treat the newly calculated values as "native" for the purpose of the next trick.

Field of vision glitch:

This is based on radically skewing the aspect ratio. In particular - retain native screen height and DPI, but reduce screen width - halve it, or even more. (the game operates in landscape mode while RCPM assumes data for portrait; you want ultra-wide landscape, that means ultra-tall, narrow portrait.)

Android doesn't change the actual aspect ratio - it just adds black stripes in the unavailable area, centrering the rest and stretching to fit - so a native res of 1080x1920 @480DPI changed to 540x1920 @480DPI means there are two black bars occupying half the screen area now.

Your screen should be one looong noodle, and the game will glitch in more than one way. But the most obvious glitch in the crystal game is that your screen now extends (both left and right) far past what it showed so far.

Getting used to playing in the new resolution takes some time&effort so at first your performance may be worse than before. You may need to get rid of the twitch to tap as soon as something shows up on the screen ;)
