Hey there!
It is time for Mine Blocks Classic 1.30, the final update of the Flash version of Mine Blocks! 
As expected, it's a smaller update, but I think you'll like what's new!
Check out the update video and full changelog below!
Please backup your worlds before playing!
Try out the new "backup everything" feature :)
Hardcore mode!
Challenge your survival skills with hardcore mode, where you don't respawn after dying.
In hard difficulties, hostile mobs spawn more frequently and zombies can spawn with armor!
If you die in hardcore, explore your world in the new spectator mode!
To make hardcore mode more fair, sneaking invulnerability was corrected, golden apple seeds were nerfed, and over 9 duplication bugs were fixed.
Hostile spawnskins!
Map makers rejoice! There is now an aggro data tag for spawnskins, which means you can make hostile and neutral custom mobs!
And you can apply armor to spawnskins... you can even go as far as to put frost walker on their boots!
New slime block physics!
Slime blocks got a major update! Entities can be launched by pistons with slime blocks, and projectiles now ricochet off of slime blocks!
Slime blocks move attached blocks when pushed by pistons, which means: flying machines!
Several bugs were fixed relating to pistons and redstone too.
Inventory shortcuts!
Navigate your inventory much faster with shift-click to instantly craft an entire stack of items, or quickly move stuff in your inventory or chests (or any other container)!
And use pick block (the middle-mouse button) to quickly update your hotbar item to the block you're hovering over!
New block types!
Improve your bamboo-based builds with new bamboo slabs, stairs, and backdrops!
There is now gold soil, which can be used to grow golden apple trees! You can craft it by surrounding a dirt block with 4 gold ingots, or by growing a golden apple tree in a gold block.
New headgear!
You can now wear mob heads. It reduces your visibility range for mobs of the same type!
Also, a bonus effect: the ender dragon head's mouth is animated when you move!
Sheep can very rarely spawn with a mustache, and you can steal it from them with shears! Fancy!
And more!
There's a full backup and restore tool, so you can be ready when Flash is gone.
Smaller things include fire blocks, iron nuggets, and 57 tweaks, fixes, & optimizations!
There are a lot of other changes, so check out the full changelog to see what's new!
See below for all additions, bug fixes, and tweaks!
