This is a really cool game. I really like the expansiveness of the hand-crafted world, and I like the feeling of exploration that one gets -- that little pause to show the title for a new region when you walk into it for the first time -- it's very Zelda-like that way, and it's a great vibe.
I like how I can talk to so many of the people, though there were often women by wells that seemed like I should be able to converse, but they were unresponsive -- almost seemed like they were possibly part of the well template, and not actual NPCs?
Regardless, it was really cool, and the storyline with resolving the conflict between the three brothers seemed interesting. Normally when I would get stuck (like in the water or underneath the world or something) then I was able to just quit and reload and it would pop me back out into the last place where I'd entered the world, but the last time I got stuck was in a cave that I couldn't seem to figure out how to get out of (screenshot attached).
Also wasn't sure what to do with the honey jar that I got, and the description I think was left-over from a different item.
Collisions are definitely the trouble-point here, but outside of that, I think you have a really solid foundation here. The cutscenes feel good, the dialog works, and the 2.5d perspective feels very natural. The island felt friendly and welcoming and it really made me want to explore more. I like atmosphere of the rundown town and it feels like the sort of place with deep history and it makes me want to learn more about the place.
I really appreciate the running shoes -- it helps SO much to be able to get around faster in the world.
A couple of other quirks -- whenever I interact with something, I need to re-enable my running shoes. Also, the GUI buttons look like they should be clickable, but it's not intuitive that one needs to only use the keyboard to interact -- it really looks like these are mouse-clickable elements, so making it a bit more clear that it's keyboard-only might help.
Overall, great job on this entry!
