Pulseboard

Your turrets don't have triggers. A pulse does.

One pulse runs the trace on your circuit board, and every component it crosses fires once. The only question is where you put things, and how often the pulse comes back around.

The shape of the board is the puzzle. One pad in the right place beats five in the wrong ones.

Drag components onto the pads, drop two of the same together to merge them, and hold the core while faults close in from every direction. Every wave you reach earns solder, including the runs you lose. Spend it on new components, permanent damage upgrades and a tougher core, then take on the next board.

Merge up to tier 5 - coverage matters more than raw damage

Losing still pays: unlocks, weapon upgrades and core reinforcement carry over
