I really liked that minimalistic minecraft/terraria freedom vibes in sound and graphical design. However, the game does not seem to work properly, so I hope, you will be receptive to some critique.
I could not really interact with anything nor in browser version, neither in downloadable one. Aside from collecting materials to complete the main task, it would be especially helpful to be able to see again what merchant has to say, since it is such a massive wall of text. As I said, you have some really nice atmosphere, however to my understanding, your game is more of a quest, than a sandbox. Also difference in resolution of character sprites, environment tiles and text is a bit jarring.
Anyway, you definitely have potential, hope to see your next game!
