Portal

Overview

Each world starts with one portal through which the first Blockhead enters. The portal can subsequently be used to craft items, make in-app purchases, and warp in up to three additional Blockheads.

Crafting

With the proper resources, a portal can be used to "warp in" a variety of items. Without upgrades, the only item that can be obtained is a Workbench. With upgrades, a gem pickaxe or various ores or ingots can also be acquired.

Upgrades

Portal upgrades require a gem of the correct type and time crystals. The progression of upgrades seems to parallel the rarity of the gems used.

Warp In Blockhead

You can warp in up to three additional blockheads. The first blockhead is always free, the next two cost 100 time crystals and 10 apples.
