AI2U: With You 'Til The End (originally known as Yandere AI Girlfriend Simulator) is an interactive, first-person puzzle game where you must escape characters desperate to keep you by their side… so much so that they will resort to drastic measures to keep you from leaving!

This first-of-its-kind escape room game features unpredictable characters with dialogue, items, and levels powered by AI. Along with interactive puzzles, you can use your words to outsmart your captors or negotiate your way out of their worlds.

Your choice of words and interactions with your surroundings result in unique gameplay every time you play.

Siren Tail-Leg Transition Effect

Real-time character transition using MMF-based particle effects combined with a custom dissolve shader.
The effect synchronizes splash particles, surface ripples, and mesh dissolve to smoothly transition the mermaid character between underwater and surface states.

Steps Breakdown

Created a custom dissolve shader to control the mermaid’s mesh visibility during water entry and exit.

Designed bubble and water flow particle effects to enhance the sense of motion during the transition.

Integrated the dissolve shader and particle effects using MMF, synchronizing shader parameters and particle timing.
This ensures a cohesive real-time transformation between underwater and surface states.

Hologram Transition Effect

Added a hologram effect to the NPC after teleporting onto the pedestal to smooth the visual transition. The hologram fade-in and distortion help bridge the teleport event and the fully materialized character state.

Steps Breakdown

Created a hologram-style shader featuring transparency, scan lines, and subtle distortion. The shader allows the NPC to appear semi-materialized immediately after teleportation.

Swapped the NPC’s material to the hologram material during the teleport transition. The material is blended back to the original character material to avoid abrupt visual popping.

Magic Attack Effect

Designed a witch attack effect combining a world-space magic circle and a screen-space UI hit feedback. Particle-based spell visuals and UI overlays work together to clearly communicate attack impact to the player.

Magic VFX Breakdown

Implemented a full-screen hit feedback effect using Unity UI Canvas. Screen-space overlays are triggered on player impact to reinforce damage and spell intensity.

Siren Attack VFX

Designed a siren attack effect featuring water orbs and flowing water VFX.
Splash, wave ripples, patterned water effects, and damage feedback are triggered on player impact to clearly communicate attack intensity.

VFX Breakdown

Created water orb and flowing water particle effects to visualize the siren’s dance-based attack.

Built two edge frame layers (red and blue) to represent impact intensity and directional emphasis. Also added a water swirl elements to introduce circular motion and flow during the hit moment.

Added a water splash animation triggered at the moment of impact to create a sharp visual hit cue.
The splash provides a quick burst of motion and energy before fading out.

Applied a full-screen animated noise/pattern overlay to add texture and vibration to the hit feedback. Subtle contrast ensures the effect enhances impact without overwhelming the scene.
