I definitely liked the theme of killing snakes with monsters. The entrance and the little, gray serpent traps in 1S1W were my favorites of the concepts. 1S2W was a really good wraithwing/serpent room too.
2W is a bit anticlimactic as it goes from a very difficult trapdoor/rattlesnake manipulation to some simple evil eye sight dodging. Snake movement manipulation + trapdoor path completion + ortho square limitations is like 8x more brain power required (for me)! Thank you for not adding brained movement to that!
2N2W only requires 1 goblin to complete, so having the other goblins behind locked doors simplifies their presence to goblin group manipulation after the serpent is gone. Ideally, they should be worth more to the room OR to the continuance of a story theme. "
You's be puzzle-part-makings uss'm goblins next puzzle times,"
they are saying.
Also, the arrow path on the bottom edge of the level confused me for a bit since it looked like I was expected to emerge from a more southerly room.
