I think I broke the scaling-resolution of the game, even if the game is in full screen, it looks tiny within it. Could you add scaling-resolution controls to the settings? Also a way to reset it?
The standard 1920x1080, but since the windows taskbar and title bar is much longer than 80 pixels, it's not easy to scale it as longer than 1000 pixels manually. 1x 2x 4x buttons for 500 1000 2000 resolution might work best in this case. Or a full screen option would work quite well. Otherwise, game is quite good (except the difficulty of the puzzles) keep up the good work!
