Thanks! and yup thats how I solved it too when play testing the level for the first time, use the blood as a reference point and move backwards and side ways until you find a new hallway.
yeah you can use the numpads to move diagonally as well and numpad5 to skip a turn, I had plans for skills and more but I was learning rust language as I was making this so 7 days wasn't enough for all the ideas
