Great game! I'm not the best at puzzle games but both the scaling in difficulty and introducing new mechanics were really smooth. I got stuck at one point with the 3 walls (stuck in between 2 walls) but was able to restart using the menu. The controls and time mechanics is solid. I think the only trouble I had was like climbing down.
I like the overall dark thematic, the music choice was great, and I like the story progression with the previous adventurer.
