When releasing the game, I ran into an incompatibility problem on older smartphones. The game either crashed or did not start.

 After examining the issue, I found out that the problem lies in the lack of support for Vulcan (the Graphical API used by Godot 4). Therefore, apparently I will be releasing two versions, for old and new devices.

For some reason, OpenGL in Godot does not support embedded postprocessing, so I made my own post-process shader, but it turned out well. You won't even notice the difference right away.
