KNOWN ISSUES:
-Gameplay controls for mobile devices still not implemented
-The gameplay board animated background gifs doesn't seem scale properly, it keeps an empty line in the bottom and depending on the platform in the left
-In some Android devices (Samsung Galaxy J4, uses Android 9) don't seem to have the buttons mapped correctly for Dual Sense controller,  and some other Android devices (Oppo A78 5G, uses Color OS variation of Android 14) doesn't seem to recognize analog sticks of any dpad.
-In all devices the Switch Pro Controller acts chaotically. It's a Godot-wise bug, not only happens in this game and may be fixed in the future. Until then we won't support this gamepad

-Stage 8: The board of the animated background gif is 1 row too tall 
-Stages 18 (clouds) and 23 (black Game Boy): the platforms with 4096 or 32768 colors (QVGA, Amiga, SNES, Neo Geo) there is a texture in the sky of the border image but not in the in-game animated background
-Stage 21: The board of the animated background gif lacks 1 row in the top
-Stage 25: Which are the proper pieces for this stage? I did put there some unused ones

TO DO:
-Add more customizable options in the settings
-Animate the loading screen
-Fix the bug for the color replacement shader for temporally removed platforms like MSX, Master System or Game Gear, with had different color depth for their RGB channels
-Fix the scaling bug seen in the upper side of the screen for the temporally removed platform CPS
-Simulate color limit per tile for marquee border backgrounds
-Simulate color limit per sprite for the gameplay window
-To disable automatically scanlines for the windowed mode when the zoom is too small to see them properly (I'd say it may be seen properly with 3x zoom and above)
