The game uses a side-scrolling perspective with multi-level building stages. Felix moves between floors, jumps across gaps, and uses his hammer to repair broken windows while dodging falling debris and other hazards. The objective is usually to fix enough damage before time runs out, and later stages increase the pressure with more frequent destruction and tighter routes. Success depends on timing, efficient movement, and choosing safe repair paths through the building.

Learn the stage layout and build a repeating route that covers the most common damage points. Repair nearby windows first so you do not get trapped by new hazards while crossing the building. Use jumps carefully and avoid committing to long detours when the screen is already crowded. In faster sections, focus on survival and consistency rather than trying to clear everything at once.
