About Grave Gauntlet
Grave Gauntlet is a survival game set inside a sketchbook that the player can paint: monsters attack, upgrades stack up, and weapons leave colour across the world. The developer, Dandey, a YouTuber who describes themself as a beginner at game development, says the game was built with Claude Opus 5.5 over two days and “a lot of prompts”: “I used AI to write the code, worked on the models, and tested each version to figure out what actually felt fun.” The video of 24 September 2026 shows the build from awkward sword animations and broken projectiles to monsters and upgrades. The developer calls the game a work in progress and says an itch.io playtest link will be added when it is ready.

“I used AI to write the code, worked on the models, and tested each version to figure out what actually felt fun.”Verification notes: Everything on this page comes from the description of the developer's YouTube video of 24 Sep 2026, re-read on 8 Nov 2026; the spoken content was not checked. The channel (about 290 subscribers) is pseudonymous and posts other first-person videos about making games with Claude, mostly on Roblox. The description promises an itch.io playtest link “when it's ready”; none had been added and no build was found on itch.io on 8 Nov 2026. The name is also used for an unrelated Geometry Dash level set. Engine and location are not stated.
