This is a great game. I love, how it transforms the same puzzle into a different one just based on your alignment. The only thing missing for me, was a different aesthetic for the doomslayer mode. After trying out the pacifist route, I hoped that doomslayer will give me red hair and “BFG division” starts playing. :D
The checkpoints were confusing, but that has already been addressed. The doomslayer route was a lot easier than the pacifist route, which is to be expected. It reminds me of some stealth games, where you can go quietly or loud. One interesting thing is, I instinctively hid from sight at the beginning, as I thought enemies would run at me when they saw me. But I quickly discovered that is not the case.
