This is an amazing game. The graphics, sound design and especially the puzzles are all excellent. There is not a single thing to dislike. Well ... I could have done with a little less grunting and stair climbing. But considering that's down to my puzzle skills (or more accurately, lack of them), I can hardly blame the game, can I now? :)
Personally, I wasn't so much reminded of Rusty Lake as of Mateusz Skutnik's submachine series. Which is most certainly not a bad thing. The slightly unsettling vibes are somewhat reminiscent of the former though.
Puzzle difficulty was spot on for me. I didn't really get stuck, but I had to keep thinking the whole time. I do like escape games and solving problems felt very rewarding. Easily one of my favourite entries this jam.
