So this quest felt a bit like a rollercoaster to me. Some things were done pretty well, others not so much.
First of all, this is definitely an improvement over your last quest, The Dark Treasure. This quest felt more playable and much more enjoyable though of course there are still several more issues that I'll come across later. As for the positives, the screen design generally looks alright, some areas could definitely use some work but I did like some of the dungeon design and overworld design. Some of the ideas you have are pretty neat and the one purple Darknut guy following you throughout the quest was pretty neat since most quests just put the antagonist at the end or the beginning and that's it. I also did like how you tried to get as many items as possible involved rather than just making use of them in one spot and never use them again, which was nice to see.
However, there are quite a lot of negatives which brought the experience down for me. Firstly, while I did say screen design was generally alright, there are a few times when some of the screen design looks quite bad or plain, especially with the trees being lined up vertically rather than diagonally like how they're intended to be used. There were a few tile errors I came across but they aren't too big of a deal. Secondly, I feel like the triggers are really inconsistent and sometimes make no sense. There are times where I think a switch needs an arrow to activate, but another switch that looks identical uses a boomerang instead. It makes things really annoying and just ends up being trial and error to find out what activates what. I would suggest to stick to one kind of switch for each item, rather than using the same combo for different triggers. Also, things like bombing a torch to get a chest doesn't make much sense at all. The dialogue in this quest was quite hard to read or understand at times, though I definitely understand English isn't your first language, so it's definitely not your fault for that, but maybe you could try to get a proof reader or something to check over the strings to see if they make sense or whatever. Definitely not necessary, but it could help. Another point I need to make is that I feel like the difficulty is kind of all over the place near the end. The constant Darknut abuse near the end kind of got crazy and make things much harder than they needed to be (even with the Gold Tunic and Master Sword) and I would probably try to use a more variety of enemies near the end rather than just spamming Darknuts everywhere. Finally, this quest felt quite linear at times and felt more like a straight path in each region rather than being more maze-like and non-linear. Of course, linearity isn't always bad, but in this case it felt kinda boring at times. Just something to consider for your next quest.
There are a couple small things I found when playing, so I'll just list them here.
This happened when I managed to walk over from the right side or the top, I think you forgot to make the treetops in the other screens solid, so this happened. I'm somehow able to walk over
these pits using the half-tile trick. I'd probably make the pits sensitive stair warps or direct warps to prevent things like this from happening. A Stalfos managed to get stuck
here. I guess you forgot to add a no enemy flag there. You forgot an undercombo on
this screen. I can somehow swim over
this tree. I can also swim over
these going out of bounds into the void.
This shop in that dragon town place sells nothing.
This bomb trigger leads me into the Triforce room, skipping the rest of the dungeon. Not sure what's going on
here. I definitely do agree with Mister Snooze though, I would try to gather a few beta testers before releasing a quest, just so that you can get rid of all the weird bugs and stuff like I've found.
Overall, this quest was decent in some parts, and could be much better in others. I'll give this one about a 2.5/5, which rounds up to a 3. You're definitely improving from your last quest though and I look forward to seeing more quests from you in the future!
