Block Block Block Patch 1.0.3 Fixes Steam Deck Performance and Camera Bugs
Block Block Block Patch 1.0.3 targets critical loading failures, Steam Deck performance hitches during room editing, and annoying camera jumping glitches.
Developer Aender Lara has released Patch 1.0.3 for Block Block Block, addressing several bugs, UI miscommunications, and performance issues on handheld hardware.
Performance and Usability
Wall and window interactions have been optimized to run smoother when moving items, directly targeting performance drops on Steam Deck. Additionally, the horizontal and vertical offset UI elements now clearly communicate their functions when operating over a vertical surface.
Critical Bug Fixes
Several crash and loading faults have been squashed. A missing deformation parameter that prevented scenes from loading correctly is resolved, and obsolete player data versions from older saves will no longer block game startup. Other fixes stop the camera from jumping when moving items too close to the floor, prevent thin or rolled items from scaling up abruptly, center window items properly on walls, and fix group deletion undo history scaling errors.
Why this patch matters
This update focuses heavily on foundational stability and performance, making it safer to load older saves and play on portable hardware.
