"Atmospheric" is how I would describe this game.
It ran reasonably well on my Windows laptop, but the framerate was a bit chunky (couldn't tell exact FPS, but maybe 20 or so) -- would have been nice to be able to adjust the graphics to run a bit better on my machine, but otherwise it was still definitely very playable.
I liked the use of lighting and atmosphere here, and the animation and movement felt clean. The collision detection felt solid, and I never glitched through the walls or any other boundaries -- even with the complex geometry in the game. That was very good.
I liked the particle effects and illumination when lighting the braziers. The discovery of the world felt good, and a couple of times, it seemed like there were false paths that I went down (green and purple lighting) -- I assume that was meant to represent false and misleading paths?
Failing near the end of some of the jumping puzzles could get frustrating at times, but I pushed through and was still able to reach the end. I really enjoyed the music at the end, and the illustration of the graphics. Overall the game felt like a visual poem to illustrate the chosen verse.
Technically, this game was extremely good. Artistically, it was solid and well-executed. The fun / gameplay was the weakest aspect, but it was still a very enjoyable experience.
Nice work!
