About 密閉の壁
About 密閉の壁
密閉の壁 is a single-player clicker and idle simulation made by shiro417. You work on the wall of a sealed room, removing blocks a little at a time and collecting the fragments they release. The browser game is hosted on itch.io and recommends a PC in landscape orientation. Its presentation uses pixel-style visuals with simple sound effects and background music. As excavation continues, the wall’s materials change across layers, moving from soil toward crystal, lava, stardust, and void.
Gameplay and choices in 密閉の壁
Play begins with the wall itself: click it, or hold the button for repeated strikes, to damage nearby blocks. Bring the cursor close to loose fragments to gather them, then spend those resources in a skill tree. You can raise striking force, working area, pickup ability, luck, and automation. Greater excavation progress opens deeper material layers, while automatic striking and collection drones allow the process to continue with less direct input.
What sets 密閉の壁 apart
The strongest hook in 密閉の壁 is its changing underground-like sequence of materials. What starts as soil can lead through crystal and lava toward stardust and void, giving each deeper layer a clear visual marker. The loop also grows beyond manual clicking: automated hits and collection drones turn a basic mining task into a gradual idle system. Pixel-style art keeps the presentation deliberately spare.
Is 密閉の壁 for you?
密閉の壁 is a good match for players who enjoy clickers, idle progression, mining themes, and small upgrade decisions. RPG-minded players may like shaping a skill tree around force, reach, gathering, luck, or automation, while strategy fans can decide which improvement supports their preferred pace. It is still in development, so expect an active work in progress rather than a complete final version. A PC browser and horizontal display are recommended.
