With the right technique you can solve it first try in 4 moves
Fun little game, one thing I would change is swap z/x because its the wrong way around compared to how it looks on the screen.
You can't install this game from inside the itch.io app, i think because you havent maked the installer or the portable version as for windows.
Switch to full screen in the game options first, then switch resolution after.
The crash only seems to happen in windowed mode, not fullscreen.
The game crashes when I try to switch resolution
