I tried level 1, moved the two stones onto the squares... and nothing happened?
Eventually I realised that the stones need to be placed on different coloured squares - I'm colour blind (red/green), and can't tell any difference at all between the stones. For the squares, I can tell one is a bit darker than the other. You might want to consider using more contrast, or a more colour-blind friendly colour palette.
Reminds me of Sokoban, which I first played more than 30 years ago!
