confirming that after a few days of revisiting, i have finally beaten the second level. I thought for sure, at first, it was impossible. I stumbled upon the first move - confusing the snake's pathfinding and letting it commit a disadvantageous path. From there, I worked out blocking with the barrels for a long long time until I finally discovered a configuration that let me freely solve the remainder of the puzzle.
Pretty difficult puzzle but super nice to solve - no hidden mechanics, just challenge your assumptions and consider where the computer would make a mistake in good faith. The snake does not read bombs as obstacles.
