Hello congratulation my friend
Your game calmed me down I needed more =)
few notes for you
- For the future make sure you have easier levels in between hard ones, otherwise at some point puzzles will become shores, like The Talos Principles 1.
- few animations would help a lot making this more dynamic ( water, leaves, trees moving etc )
- I would show both characters path in transparency when you click on one to set his path, that way you can plan you movements better and anticipate the other characters movement.
-Keep it up, this is a great little game.
