At first, I was pretty confused at the green room puzzle since I thought I'm supposed to input the symbols for Noki and the Minotaur themselves and not the clues I learned from them. After some wandering around though, I noticed the second symbol and everything clicked into place. Soon after, I made it to the exit. The path to the door should've been a bit more visible though in my opinion.
I do wish there was some sort of alternate pacifist ending where you spare the Minotaur or try to persuade them into letting you pass through; I think that would make the game a bit more interesting. The camera rotation was also slightly disorienting to get used to, but it was mostly fine.
Overall, the dialogue system is very well-made, the story is cool, and the concept could be expanded by having more rooms after the initial one that require different flame colours to activate (that way, you'd have to use the lantern more).
