I know that everyone of your players are unique and you'll never be able to make everyone happy, but I would like to share my feedback with you. Most of the items you listed above look great! Having said that, I know "0" about programming a game, especially one as large as Ylands. Just for the record, I think you all have done an amazing job and this is my first experience with giving feedback to a developer so I'm glad it is with this game. From the comments I've read from others, your team is exceptional and somewhat uncommon in the gaming world.
Of the items you shared, here are my favorites: 1) Baby animals, 2) Lakes and rivers, 3) Friendly NPCs, 4) Add body sizes for characters, and 5) more block variety.
In addition, I would love to see 1) Part of the block variety could be wallpaper or very thin blocks, 2) real waterfalls, and 3) ability to fight when riding or diving,
Thanks again for all the hard work you've all put in on this game, it definitely shows! Sandy
