"An Action RPG Souls-Like set in a fantasy world based off Italian folklore and culture. It is defined as a Souls-Like but unlike other souls-likes, we are depicting a world based off Italian summer.
The Universe is a Story, which unfolds and weaves the ever-changing tapestry, making up Reality Itself. Until a group of extraordinary individuals, used the power of the Story to trap it on paper – creating the Canovaccio.
Captured in the Canovaccio, the world has since degraded, becoming an empty – yet beautiful – husk…", developed by Jyamma Games

Whatever happened to Celeste?

Stray

Why? However many games involving cats you think I have or I actually have, it's just not enough. I need more and by more, I specifically need the ones where the player character is a cat.

Brigand: Oaxaca

"Brigand: Oaxaca is a highly difficult post-apocalyptic RPG/FPS set in Mexico. The story will take you from a banana plantation into dark toxic caverns, to the sprawling city of Pochutla, to the flooded coastline, to deadly demon-infested jungles, and more."

It´s like a low budget Deus Ex in Mexico. Good reviews on steam. The developer submitted the game to GOG a couple of times, but to no avail.

Here's the wishlist link:

I re-entered after a long hiatus because I was given a more powerful PC last year, but the resolution refused to cooperate and I couldn't see anything clearly. A pity, I'm at level 27 or so with just the best dagger ever.
