Very cool concept, and impressive that you got this kind of procedural generation working! It's very cool that the player can explore such a big world, and I absolutely love the variety in quests. There are a couple little nitpicky things that I think could make the game even better.
- The movement controls would probably be better on WASD instead of arrows, since if would make the spacebar accessible to the thumb of the left hand. Using the arrows and the mouse meant I couldn't reach the spacebar in regular gameplay.
- The rabbit's foot makes me move a little too fast, so much that it becomes hard to pick up small items.
- I also accidentally wandered away from enemies at first and then had to really search to find them again after that. If there was an area boundary or a general indicator of enemy position, it would make getting lost less likely.
- Lastly, it seems like the music is localized to a certain area, so I spent a lot of my playtime not getting to listen to it.
All in all, very impressive work!
