Thanks I'm glad you liked it! The minimalist aesthetic was probably in part aided by the fact that we didn't have time to make multiple different bushes, or a tree.
I'm pleased that you've also noticed what I was going for in puzzle design. When I realized that grass tiles were mechanically the same as road tiles I knew I could just throw red herrings that look like solutions into a lot of the puzzles to fox the player. Its a hilariously easy way to encourage players to try something in a puzzle like this because players take a long time to realize that the road is mainly a distraction.
