Wow, what a polished game! It was a really fun quirky vibe, and I enjoyed stomping around the shop to find the right orders. The procedural generation and similar items with different colors are a nice touch to make you stop and pause for a moment about whether this is really the yellow book... or if it's orange and there's a different yellow book somewhere else! (there wasn't)
The game ran fine on my PC, but it was a little blurry somehow (maybe motion blur?). It made it hard to see what items I needed to find while moving, and I got a bit dizzy if I was looking far away from Stumpy to find a specific item.
