After a few levels of gameplay, the colors on the screen got reverted. Not only in game, but also in the Android system. I turned it on and off or maybe switched "inverted colors" in system options panel. It fixed the colors. After that, the screen during everyday system use had glitches/ freezes.

After factory reset, everything was fine. Unitl I played "Phone Destroyer". The colors got reverted. Also all the texts and visual elements (panels/buttons) got reverted horizontally and vertically. It disappeared after turning phone on and off.

I am not sure is it a game bug or my phone is just broken. But all the visual glitches started appearing when I was playing your game. That's why I decided to inform you. Just in case. Nice game by the way.
