Would you be able to update the README file to include instructions on how to remove the pinch zoom and camera pan? Because at the moment when trying to click and drag to fill in multiple squares it's just dragging the image around and having to click each individual tile is noisy and annoying.
I'm also having trouble getting my own images into the game, I've saved them as black and white PNGs with no transparency, they're both only 5x5 pixels, and I've set the image properties in the inspector to match the example in the README but the game just sits on the loading screen.
