Hello and hi!
In next update with earlier announcement UI update and gamepad support will be added Extra Modes with.. ahem, BIG MAZE.
It's in 3x larger than usual maze. And looks pretty simple. Yeah, it's because that large maze showed 3 FPS at old machine [read laptop] and unstabel FPS [60-110] at modern. Even if i made several levels of LOD's. But hey now it's look kind of "retro" . So right now it show near 30 fps at old machines and stable FPS at modern.
P.S. I'll add achievement as reward to all who completed this maze.
