You are right about the data: the original El Nath maps are marked as slippery ground (26 of the 40 El Nath maps carry it, El Nath town included), and seven shoes carry the matching anti-slip value, so this is real and not invented. Our movement does not read that setting yet, and the exact way the original game combines the slippery ground with those shoes still needs to be worked out properly before we change how walking feels. Nothing has changed yet; this stays open.

Thanks Masamune, you were right. The original game makes El Nath slippery, and we now do the same. It comes from the map itself: El Nath town and the snowfields around it carry a "slippery ground" setting (26 El Nath maps), while the mines and dungeons below don't. That matches what you described.

What changed:
- On those maps your character still reaches full walking speed, but builds it up slowly. When you let go or turn round you slide about 100 pixels before stopping.
- Snowshoes (Red, Blue, Green, Black, Yellow, Purple) grip the ice, so you stop almost at once. Riding a mount grips too, as in the original.
- While working on this we also matched the rest of walking to the original: a slightly longer stop on ordinary ground (a few pixels of slide), faster walking downhill and slower uphill, and jumps that keep your running speed.

This is fixed in the code and goes out with tonight's update. To check once it's live: walk around El Nath town without Snowshoes and let go of the arrow key (you should slide), then put on any Snowshoes and try again (you should stop right away). The Spikes on Shoes scroll's anti-slip effect isn't hooked up yet; that's a separate follow-up.

This is now live (today's update). Bare-foot on El Nath's icy maps you slide when you stop or turn; in any Snowshoes, or riding a mount, you stop right away. Please give it a try (walk around El Nath town, let go of the arrow key, then try again in Snowshoes) and tell us if anything feels off. The Spikes on Shoes scroll's anti-slip effect is still a separate follow-up.
