Hmmm, this is quite the interesting Fallout/Zelda 2 adventure you got here!
Was definitely quite impressed with it in a lot of respects, obviously starting out strong with the very stylish and cinematic (albeit a bit over-indulgent) opening that plays when you start. But the game itself also had such a huge scale and variety to it: side-scrolling action sequences alongside top-down exploration, so many people to talk to and objects to examine with loads of flavorful text, a huge world map with all sorts of locations and random encounters, tons of secrets hidden around, lots of quests and unlockables...it goes on and on! Clearly, a lot of effort and love has been put into crafting a huge adventure here!
Having said that, though, the game also felt incredibly awkward, stuttery and laggy to play at times. Combat was particularly bad feeling with no satisfying and intuitive feedback to it: just made me never feel like I was connecting with my blows, and I was constantly getting surprised when I got hit despite being so far away or giving my best efforts to dodge the telegraphed attacks. While combat was the worst, the awkwardness also extended to other elements, like the pause menu taking so long to come up after a press, dropped inputs, or weird collision detection and such. I understand these might be limitations of the engine, and while you have my sympathies, it doesn't stop it from feeling bad nonetheless.
Apart from that, there were some other minor complaints, like how tricky it can be to keep track of quests: it seems like the log only tracks your main quest, but none of the other quests like tracking down the child. Yes, if you go back to the quest giver, they'll likely tell you something about what your current setup is, but still, that's so inconvenient and they didn't always provide all of the details you needed.
I dunno, I'm a bit mixed on this one. Like I said, I really appreciate this huge world you've built with so many characters and quests and such, but as much as I wanted to keep going, I couldn't get over how sluggish and bad the combat and general movement felt: it just sapped my motivation. Almost felt like the game would be much better if it scrapped combat and just stuck to exploring: perhaps that might better fit the limitations of the engine, assuming there is no better way.
