I can confirm the Linux build works.
The "No I am poor" line in the inn is genuinely hilarious. A friend posted a no-context clip of that in a group chat (they're also a participant in this jam) and I sussed out which game it was to encounter it for myself. Intentional or not, it is perfect.
Movement feels a tad stiff for the action-adventure combat the game expects. Taking a note from the GB Legend of Zelda game might be useful here, allowing diagonal movement for better positioning and mobility. Alternatively, early Ys bump combat could be an avenue worth exploring instead.
The soundtrack was good. The overworld map music was a cut above the other tunes IMO.
Graphics are also good. Nothing struck me as lacking visually. Which, under the time crunch of a jam, is a good sign.
