The current shop set up is just hard to deal with, move them to a different "realm" out of serbule maybe have a portal in each city that leads to the same shopping center (but portal back only returns you to where you came from), this will also help reduce lag spikes in serbule proper i'm certain and won't kill the central integrity this game has achieved so far.
Put a run skill in the game that affects running faster (not insane obviously)
Put a jumping skill in the game that affects distance and height slightly (maybe for access to certain dungeons or just for more fun)
or possibly a skill like "athletics" that does swimming/climbing/jumping/running, certain i'm not the only one to think of this but would LOVE to see this in game
lastly the boxes to click on portals/trees/etc need to be centered to view, moving the camera straight up in the air is quite frustrating even in alpha stage thanks if you're reading this.
