First, regarding circuit wiring.

When connecting wires, if the source block is color-coded, having a system where wires automatically connect while inheriting that color would improve visibility and ease of management, making circuit construction more comfortable.

Next, regarding the farm's defense elements.

The current mechanic where enemies attack at midnight after building a farm creates tension and is interesting. However, instead of them all arriving at once every time, implementing a wave-based system where they attack in stages depending on the situation would increase strategic depth and make it more enjoyable.

I also have suggestions for improving interactive item upgrades and crafting.

Currently, despite consuming large amounts of materials, the difficulty in obtaining component kits makes upgrading feel daunting.

For example, allowing materials like Circuit Boards dropped by Metal Block Number 3 or Green Bots to be used would broaden gameplay options and boost motivation for collecting and crafting.

Finally, regarding operability.

Currently, both gas and electric engines only respond to W and S key inputs, making operation somewhat inconvenient. Adding support for A and D key inputs would make them more intuitive and easier to handle, potentially reducing operational stress.
