Wiggly Paint is a minimalistic drawing simulator where movement defines outcome. The player controls a soft, flexible brush that behaves according to motion and speed, leaving behind colorful trails on a blank canvas. There are no characters, objectives, or competitive systems — only the interaction between user input and visual response. The entire experience occurs within a single space that functions as both environment and interface. Each session begins with an empty screen and ends when the user decides to reset or save their creation.

Gameplay Logic and User Actions

The design of Wiggly Paint revolves around continuous feedback. Every gesture immediately alters the form and direction of the brush.
The main gameplay components include:

•         A reactive brush that bends, stretches, and oscillates with movement.
•         Basic tools for changing color, brush thickness, or line persistence.
•         Real-time response to touch, mouse, or stylus input.
•         Optional reset and export functions for managing sessions.
  Because each movement produces unpredictable shapes, no two drawings are identical. The focus lies on discovering how small variations in control affect the resulting visual patterns.

Interface and System Behavior

The interface of Wiggly Paint maintains simplicity for uninterrupted interaction. The canvas occupies the full display, while tool icons appear along the edge for quick access. The player can alter brush attributes mid-session without pausing. There is no distinction between menus and play state — the process is seamless. This approach removes barriers between action and creation, ensuring the experience feels immediate. The program reacts instantly to input, emphasizing timing and precision of motion rather than composition planning.

Technical Composition and Functionality

Wiggly Paint uses a lightweight two-dimensional rendering system with simulated elasticity. The brush acts as a chain of connected nodes that move under a soft-physics algorithm, creating delayed response and fluid deformation. Colors mix naturally when paths overlap, producing layered gradients. The software records input velocity and translates it into brush dynamics, creating visual variation between fast and slow movements. These technical systems allow complex visual outcomes through simple mechanical behavior, maintaining stability across hardware platforms.
