Scary sewer game with gorillas with a quests shop and monster upgrades
Some UI I vibe coded in 2 seconds one shot prompt for my upcoming game with the new Mythos Model (Opus 5.5)
1:27Claude Opus 5.5 not only made a MapleStory clone for me, it also used ffmpeg and wrote an automated gameplay script to produce the trailer I was too lazy to record. The game took 1 prompt ("Build a MapleStory clone in Raylib-cs."), then another prompt for the trailer.
0:36付喪神が棲みついた古い蔵へ潜る、
ローグライク『よろず蔵』。
Opus 5.5の力を借りて作った、
ドット絵のミニゲームです。
神器を持ち帰るたびに灯りが増え、
さびれていた宿場町にも、
少しずつ人と賑わいが戻ってきます🐰
2:21Third iteration with Opus 5.5 medium.
I am in awe. It turned blender, image-gen, and three.js into this beauty, which runs on your browser.
An understatement to say that Anthropic cooked. You are looking at the future of game dev.
0:30I turned this into a full game with unity cli + opus 5.5, also opus did this full demo video, it played the game with multiple characters and spliced together the best bits, holy shit we're in the AGI era. Play it on your browser here: https://rehan-remade.github.io/hollow-crown/
1:08Opus5.5はゲーム開発能力が飛躍的向上！という驚き屋ニュースに「ほんまか？」と疑いながら、試しに「SEKIROを一本指で遊べるようにして」と頼んでみた結果。
ほんまや......。仕事なくなるかもしれん
1:00Opus 5.5でClaw'dちゃんが音楽に合わせて宇宙を駆け巡るレトロゲーム作ってみた！！
音楽のクオリティも半端ないから聞いてみてほしい
4:00Opus 5.5: reverse-engineer this Commodore 64 game (Impossible Mission) and create a @godotengine version of it that looks like a 16-bit console port.
(note that I'm not very good at playing this)
2:10Opus 5.5 medium, a few iterations later.
We got symbiote suit, better animations and models, and gameplay mechanics. City overhaul is still work in progress.
Again, made from scratch in three.js and blender.
