Nice game! I enjoyed the dialogue and how there were different dialogue options. I like the pixel art and the retro adventure game feel.
The ending I found felt abrupt. After I gave the rat the ring, then gave the guy the key, a couple lines of dialogue later, the game ends rather suddenly.
Does the game have multiple endings? I never did figure out what to do with the fruit or the man by the flags. I managed to get the man's attention with barking, but I didn't know what to do after that. I feel like there's something more to do in that section that I haven't figured out yet.
I think it would help make the movement less tedious if you could just hold the button to move rather than repeatedly tapping.
Overall, a really interesting game. I feel like there might still be more to discover and I enjoyed the writing. Nice job!
