I absolutely love this little game. So much gross charm and personality. I adore your art style, and this is a peak representation about what I love about it.
The game (or rather, as you say, "toy-puzzle") does a great job teaching the player how to walk through it without really getting stuck, without at all feeling hand-holdy. I have no complaints about the gameplay; it does everything it set out to.
The page text is great; gives all the info it should. I only wish the game page's theme was edited to give some colors to the page. The background 2 could be set to the same color as the monster's flesh, making it appear to encompass the entire webpage. I also wish the ability to fullscreen was toggled on within itch settings, as it always should be.
