Inkblood

Here is an excerpt from Inkblood's Steam description:

Uncover the truth - You are uniquely equipped to solve this mystery. Besides your wit, keen eye, and intuition, your carriage provides you with some more… advanced tools. Inspect the clues, take photos of everything important, compile a case file and dial your overseer once you have a strong theory.

Explore the land - Don’t expect to find everything in one place. The investigation will surely have you riding back and forth in some bizarre, perhaps even unsettling locations. Just tap the map on the coachman’s back to choose your next stop, whether it’s the city of Inqburg, deadly swamps, abandoned villages, or rite sites.

Dwell into the past - You are equipped with a magnifying glass, which allows you to peek into the past. Use it: nothing is certain in the present until the past is untangled. Wonder what the villagers were up to last night? Peek into that fragment of the past through their windows!

Eradicate the occult - It is nothing short of foolish to assume one case has no relation to another. In your position, you’re expected to see the big picture - no detail is insignificant, and sometimes a small clue from an old case might lead to the greatest of revelations.
