Turn-Based Roguelike 'Dungeon Sookuma,' Built with an AI Agent, Gets a Free Steam Demo

On October 10, 2026, the verified X account @kaigooddev introduced a turn-based roguelike called "Dungeon Sookuma," described as built with an AI agent and heading toward a Steam release. According to the post, a free demo is playable on Windows and macOS, and the developer is waiting for feedback on the first five minutes of play and the game feel.

As introduced in the post, "Dungeon Sookuma" is a turn-based roguelike in which a baby bear explores a dream dungeon. It is described as supporting combinations of 14 lineages and 19 classes. The genre, premise, and combination counts all come from that post's wording, so the actual build should be checked directly in the demo.

Free Demo and Platforms

The post states that a free demo is playable on Windows and macOS. The linked demo destination is the Steam store page (app ID 5045950, Dungeon_Sookuma). A follow-up post from the same author links both a VibeCrew intro page (ship/10385) and the Steam demo page.

• Platforms (as stated in the post): Windows, macOS
• Price (as stated in the post): free demo
• Intro page link: VibeCrew ship/10385
• Demo link: Steam Dungeon_Sookuma page

The actual contents of the Steam and VibeCrew pages were not verified as part of this report. Pricing, system requirements, and build status should be judged against the latest wording on the store page.

Feedback the Developer Asked For

The explicit request in the post is feedback on "the first five minutes of play" and "the game feel." Given that focus on onboarding friction and early controls, the natural form is to play the demo and comment on movement, selection, and combat input flow plus readability in the opening section. The channel is not pinned down by the posts alone — whether replies, comments, or the intro page — so it is safer to check the linked intro path for how to submit feedback.

Verified Scope and Limits

This report rests on two X posts dated October 10, 2026. That date is the posting time, not the game's release date. The phrase "built with an AI agent" likewise relays the post's own description; no independent verification of tools, work split, or development scale is included. Before playing, check the Steam page for system requirements and the demo's scope.
