Tech tree planner
The tree is drawn in its real shape: nodes are not stacked in a single column, they split into branches and merge back, exactly as in the game. Tick what you are aiming for — prerequisites are enforced, and the potion cost and research time add up.
↔ Drag the tree sideways to explore it.

How it works
How to read
The shape comes from the game config: each category is one single continuous tree (tiers are merely slices of layers, and a prerequisite can cross a tier). A layer holds one or two nodes: that is where the tree branches, and it merges again on a node that requires two prerequisites. A node costs by its tier, never by its effect — hit "All of tier 0": every tier-0 node across the three trees costs less than one single tier-4 node (26,326 potions).
