Irrelevant for most categories, but I felt like I'd post this here. This is a list of all the sigil puzzles solutions, minimizing rotations. The cost function I'm currently using assumes each rotation is equal cost, if you'd like me to run the algorithm assuming e.g. 3 rotations per piece is 2x as expensive as 2 rotations, just post here.

ASCII solutions Python code

Edit: I don't have solutions for Road to Gehenna DLC because I didn't ever find the original piece rotations. Edit2: DLC solutions posted; list updated to include right-click pickups.

Hey that;s pretty interesting. Good job! I believe this could help for some of the larger, more complex puzzles.
