<aside> 🌳 Skilltree & Prestige is the post-Rebirth progression loop: a node-graph of purchasable skills gated by reveal, paid for with Coins or Prestige, and refilled every time the player Rebirths (resets the run, banks Collection Book payouts into the real Prestige balance).

Source: Assets/Project Files/Game/Scripts/Skilltree

SkilltreeDatabase - a ScriptableObject registry of SkillNodeData entries. Authored through the custom node-graph editor, not by hand in the Inspector.
SkillNodeData - one node: links a BaseUpgrade asset, a canvas position, an optional per-node prefab override, its outgoing connections, and whether it is the always-visible root.
SkilltreeButton - the HUD entry point. Shows a notification dot when any revealed node is affordable, and a small pending-Prestige preview when a Rebirth right now would grant gems.
SkilltreePanelController - static, stateless reveal/affordability logic shared by the panel and the HUD button.
UISkilltree - the main panel: pan/zoom node canvas, connectors between nodes, an "about" inspector for the selected node, and the Rebirth banner.
UISkillNode - one node's visual: icon, affordable/unaffordable/maxed border tint, selection highlight, purchase/reveal bounce.
UISkilltreeCanvasDrag - the pannable, pinch/scroll-zoomable, clamped canvas the node graph lives on.
RebirthController - the Rebirth flow itself: resets the run, zeroes Coins, resets every active upgrade's per-run state, banks this session's pending Prestige gems into the real balance, and despawns every live chest, item drop, Frost, and Tentacles object left on the field.
UIRebirthCinematic - the full-screen slide-in/hold/slide-out cinematic played while a Rebirth resolves.
HelpingHandController - the auto-clicking hand: once its Skilltree upgrade is unlocked, it periodically taps the main button on its own.

Rebirth & Prestige

Prestige is spent on Skilltree nodes and earned by Rebirthing. The Collection Book pays Prestige into a pending balance the moment items are collected, but that amount only becomes spendable once the player actually Rebirths, which also resets the run.

Skilltree panel & node visuals

A node is revealed once it is the root, or any node linking to it has been purchased (SkilltreePanelController.IsRevealed). UISkilltree builds every node and connector once and toggles them active/inactive as reveal state changes, animating a bounce/grow-in on newly revealed content instead of rebuilding the graph.

Helping Hand

Helping Hand is a Skilltree node effect, not a standalone system: once its HelpingHandUpgrade (type UpgradeType.HelpingHandSkilltree) reaches an unlocked stage, HelpingHandController starts a self-perpetuating loop that calls MainButtonBehavior.OnObjectClicked() directly on an interval, the exact same entry point a real tap uses, so an auto-tap is indistinguishable downstream from a manual one. The loop pauses while InputBlocker.IsBlocked is set (e.g. during the Rebirth cinematic) and resumes on its own once unblocked.

Editor tooling

`SkilltreeGraphEditorWindow`

Open via Watermelon > Skilltree > Graph Editor, or the Open Graph Editor button on a SkilltreeDatabase's Inspector. A headless-GUI tool (no GraphView dependency) operating directly on the database asset through SerializedObject, with full Undo support.

Left-drag empty canvas to pan, mouse wheel to zoom (cursor-anchored, same convention as the in-game canvas).
Left-click a node to select it (also pings its linked upgrade asset in the Project window); left-drag a selected node to move it, hold Shift to snap to the grid.
Right-click a node for Add Connection - a live dotted line follows the cursor until the next click, which either links to the clicked node or cancels (empty space, or Esc).
Delete deletes the selected node and cleans up dangling connections. Both shortcuts are suppressed while a text field (e.g. a node's id) has keyboard focus.

`AddSkillNodeWindow`

Modal opened by the Graph Editor's Add Node button. Two tabs: Existing Upgrade picks any BaseUpgrade asset via an object field; New Upgrade takes a title and a concrete BaseUpgrade subclass (every non-abstract type found via TypeCache) and creates the asset under Assets/Project Files/Data/Skilltree. Either way the picked/created upgrade is handed back to the Graph Editor, which adds the actual node.

`SkilltreeDatabaseEditor`

Adds an Open Graph Editor button below the default Inspector on any SkilltreeDatabase asset, launching SkilltreeGraphEditorWindow pre-loaded with that asset.
