I'm intrigued in this game due to the gameplay as well as the pixel graphics. Here are some issues I've experienced:
My phone has Android 11, 1440 x 3120 screen with 19.5:9 ratio. I get a prompt "This app was built for an older version of Android" when launching the game. It also doesn't scale properly on my phone. Some texts are illegible due to the poor pixel count.
I hope you could add support for gamepad on phone and let the player hide the touch buttons, thus go fullscreen.
Wish to see a completed version in the future.
