I liked that you needed room on the tongue to "stick" objects to it. A few times had to reorganize which felt rediculous but fun. I also liked how it was randomly generated so it made hunting for expensive items fun for longer.
However, I'd say it would've been better without the knights that make you reset on contact. Too punishing and too hard to anticipate. Maybe if they were just on a patrol instead of following you? Frankly just exploring, and fighting the time limit and my own greed of trying futily to stick more things on my tongue was challenging enough and quite compelling!
