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!
Or two different shapes, because there are too many different color blindnesses.
Board games started marking counters many years ago. Sometimes their colors are so similar even for non color blind people. I couldn't get a black from dark blue counter two nights ago, the light at the table was not great. And yellow looked a pale gray.
Examples for the game: the red stone could have a empty circle mark on the top it, the green one could have a circle with a dot inside. The destination squares would be marked with the empty circle and the dotted circle.
The rule of thumb for this sort of thing is to never rely on color alone to convey important information. Shapes and patterns and textures are much preferable to simple color variations.
This would be great. It looks like at the top end there might be a third stone. So square, triangle, circle. And where they go on the board marked with the same shape would be very intuitive even with no color at all.
I think square, circle, octagon would make the most sense. Or maybe diamond (rotated square) instead of octagon. That way adjacent stone would always touch.
I had the same experience with Level 1, except I'm not colorblind but I was using a grayscale filter on my phone for other reasons. Thank you for calling this out!
