Not my preference in game type...
...but overall, this offered some of the more unique puzzles I've seen. Well done.
Most of the "puzzles" in this genre look like someone sneezed on a canvas asking you to avoid some random pixel. You've actually put effort in, and it's appreciated.
What would really set this off would be an upgrade to the graphics. You could perhaps add a theme to the puzzle(s) leaning towards a focus market, such as a pixie/faerie (suits a small 'glowing dot' representation) trying to get through the forest, avoiding snakes and logs etc, or more of an Indy Jones / Lara Croft style trap avoidance. This way you can substitute granite blocks images to replace the plain grey, or use a snake graphic of a similar shape.
Adding music and sound effects would add to the polish of this project.
Hope this helps.
