Grasshopper's Cafe
GamesSixteen weeks between hustle and YOLO — your choices keep the cafe alive. A cafe management game for Windows, built with Unity.

Palm City Run
GamesA noir top-down detective game set in the Palm City universe. A casino heist, a 30-second gap in the CCTV, seven suspects. Canvas the city, gather evidence, and name the culprit — while the clock and your drowsiness gauge press down on the investigation. Detective customization, 4 languages.

Emotion Contagion
GamesA top-down crowd-contagion puzzle arcade: click one person in a city square and watch euphoria cascade through the crowd. Maximize chains with combos and burst gauges to hit the target infection rate. 24+ levels, 6 city types, 5 special citizens (golden influencers and more), plus a free-play Zen mode.

Palm City
GamesA survival life-sim: arrive in a strange city with ₩50,000 and a suitcase, and work your way to riches. Manage hunger, fun and health through day/night cycles, find jobs, talk to neighbors. Falling down is a comma, not a period — settle up and try again. 4 languages, colorblind mode.

Crazy Office
GamesA management sim that transplants Aesop's fables into a modern office. Alternate between a turn-based campaign of quarterly trade-offs (cash, product, morale, reputation) and a real-time office tycoon mode where you walk the floor hiring and investing. Four campaigns, a stamp-collection meta, and cel-shaded isometric art.

Store Media
UtilsA Unity editor tool that auto-generates store-listing media from the open scene. It computes scene bounds, renders orbit stills from multiple viewpoints (4 store-ready resolutions) and a 300-frame flythrough sequence, then converts to MP4/GIF via ffmpeg — all without entering play mode.

Telemetry
UtilsUltra-light play telemetry that hooks into your game with 3 lines of code. The C# logger records player positions and events (deaths, pickups) as JSONL; the Python tool merges sessions and renders heatmaps over a top-down map screenshot — including the exact coordinates where players linger most.

SoakBot
UtilsA soak-test bot that runs your game overnight, watching for crashes, freezes and softlocks. It tails Unity Player.log for exceptions, samples memory to estimate leak slopes (MB/hour), and has an HTML report waiting for you in the morning. Optional auto-restart on crash.

GameFeel Tester
UtilsA bot that measures a game's feel automatically. It injects randomized input while tracking input-to-response latency (ms), freezes, black screens and softlocks, visual variety, and audio silence/clipping. Optionally narrates scenes with a vision model and produces an AI-written verdict on fun, difficulty and feel after each session.

PerfBench
UtilsA CLI benchmark that launches your built game and measures load time, refresh rate (avg/min/1% low), hitches and peak memory, then compares against a baseline run to flag performance regressions automatically. Results are saved as JSON plus a self-contained HTML report.

SceneLint
UtilsA scene linter that automatically inspects the open Unity scene for quality issues — broken (pink) materials, missing scripts, missing colliders, floating objects, z-fighting duplicates and more across 8 checks, graded Error/Warning/Info. Click a finding to jump to the object. Exports Markdown/JSON reports.

PolyMap Generator
UtilsA Unity editor extension that builds complete game scenes from low-poly art packs (Synty POLYGON and others) at the click of a button. Seven layout modes — city, dungeon, cave, village, island, multi-storey interior, race track — generated deterministically from a seed, with automatic road-connectivity and overlap validation. Unity 6 + URP.

GLOOP
GamesDevour the city! Roll the green blob GLOOP through a low-poly city, absorbing everything in your path to grow ever bigger. Collect biomass, upgrade, and swallow the whole town.

Architect of Collapse
GamesArchitect of Collapse — a demolition puzzle game where you strategically bring structures down to hit target scores. Includes stage progression, daily challenges and an upgrade system.

SYNC
GamesA first-person rhythm action game — race down a cyberpunk highway and strike incoming objects on the beat. Features NORMAL/HARDCORE/ZEN/DAILY modes, neon theme collections (CYBER, VAPORWAVE, MATRIX and more), missions and record tracking. Available in 4 languages.
