Maybe there should be a master mode for blockheads that would be even harder then expert mode. This would be an in-app purchase or an unlockable after 30 days of play time. those who played before the update would unlock it instantly.
This mode would be the hardest in the game.
-Only one life, die and its game over.
-Only 2 blockheads allowed.
-inventory space lessened to 5 inventory spaces.
-Items are the same recipe as expert but each item requires an upgrade
-Baskets lessened to 2 inventory spaces
-Every mob is hostile
-Every hostile mob attacks instantly.
-Cave trolls have 10x the health they used too.
-Cave trolls die once they reach the surface.
-Food is more scarce
-Compost has even more reduced effects. (Plants do not last forever anymore)
-Gem pickaxes (amethyst, sapphire, emerald, etc) no more
-Gold beds now have reduced effects
-Crafting now takes 1 minute and 30 seconds for each and every thing.
-Workbenches now have triple the upgrades. 58 in total.
-Teleporting is now gone
-Trade portals are now gone
-Health set to normal but you now take triple damage
-Blockheads now have stamina and if they run out they can’t climb things
-Health is now half of what it used to be
-Titanium sword deals less damage to blockheads and mobs
-The ownership sign now requires 10 time crystals, 1 sign and 12 gold
-Electricity now shocks you
-Blocks now collapse on you if not supported for at least 4 blocks.
I know this is overkill but this is just an idea.
Nothing of this mode can be adjusted via custom rules. and custom mode for this is not allowed.
