I really liked the game mechanics and the overall concept of the game. The music and atmosphere are very pleasant. However, I think it might be helpful to explain to players what exactly they are supposed to do and how to play — that’s just my personal opinion.
I often make games without clear explanations of what to do or how to play as well, so my games sometimes feel difficult to players. But I don’t see that as a drawback — rather, I see it as part of a game’s individuality. I actually enjoy challenging games, and my own games are like that too.
That’s why I really liked your game. Great job!
