The parts of the game that were there, were okay. The mansion is beautifully done, and the environment is fantastic. I would love to see it completed, but the puzzles are bugged and you have to exit to menu and jump back in. Floating arms, notes already read re-appearing, and key items not letting you pick them up if you manage to access them out of order are just a few of the bugs encountered. Performance could definitely be optimized. FPS tanks frequently even on the lowest available settings on my ROG Zephyrus G14 RTX 3080 and AMD Ryzen 9 with SSD and 16 cores... so not sure it was optimized for my system, maybe you will have better luck. Based on other games of the genre I would say that this game, which was available in March of 2021, is now about 15-20% complete and has been since 2021, so it might be safe to say this is abandonware at this point. If the devs see this, please finish this title, it is looking great so far.
