The closest two zoom levels don’t work IIRC to cut down on bandwidth, but it still looks awesome. ;D
Big post-holiday update - new block types, biome colours and more options to control player and sign markers.

If you’re using this, please consider donating to charity. You’ll get a cool in-map badge!
Thanks.
