Ver1.0.5Update
Replaced the 3D model of some characters.
The biggest feature is that it produces state changes such as petrification in real time until it becomes incapacitated. Multiple types of materials can be selected for petrification. The content of the game is an avoidant STG where the ending branches depending on the action in the boss battle.

A build is one published version of the game's files on a branch. Steam assigns a new build ID every time the developer pushes an update, so this list is the update history of the app. The files inside a build (depot manifests) are only readable with an account that owns the game, which SteamRaw does not have yet, so build contents are not shown.
