A Unity / C# soft-body physics prototype focused on slime deformation and movement through a 2D environment.

• Developed the body using Rigidbody2D, distance joints, and springs, with shape recovery, compression pressure, and a procedural mesh for deformation.
• Implemented buffered jumping, coyote time, full-body reset, and contact-aware force handling; built a sandbox for slopes, landings, and tight spaces.
