This is a very well-done puzzle adventure game! To me, it's quite reminiscent of the Zero Escape games in terms of gameplay and design. Here's part 1 of 3 of my playthrough, if anyone's interested:
I waited until the Steam release with its difficulty changes to play it because the comments seemed to indicate that the puzzles were very hard when it was originally released and I think it's a good idea that I did! I'm generally pretty horrible at puzzle-solving, but at least on the default difficulty, I eventually was able to figure them out (though sometimes I felt I just got lucky).My only frustration is how there are two objects in the last room that are easily missable (the ones you need to click on to unlock one of the endings). The highlighted area for one of them is just so tiny compared to everything else.
Otherwise, everything about the game is well put together and very professional. Cauttione himself being the main star with his eye-catching character design and dynamic animations. Though, I still don't know if I can forgive him for all the extremely gruesome deaths he inflicts on me! 😩
