Hold the line
Enemies walk a fixed path across the grid. Spend credits on towers beside that path, then upgrade the ones that are pulling their weight and repair the ones taking fire. Anything that reaches the end costs you a life.
Build towers, hold the grid, and don't let anything reach the end of the line.
Click the board first so it hears your keyboard · 1–8 pick a tower · click a tile to build (Shift+click keeps building, Esc cancels)
Space pause · F change speed · ` dev panel · SEND NOW starts the next wave early for bonus credits
Enemies walk a fixed path across the grid. Spend credits on towers beside that path, then upgrade the ones that are pulling their weight and repair the ones taking fire. Anything that reaches the end costs you a life.
Some enemies deflect bullets, some carry shields, some shoot your towers down. Flyers ignore the path completely and only certain towers can reach them — so build a mix, not eight of the same thing.
Hit ⚙ DEV (or `) to open the tuning panel: damage, range, costs, wave size, enemy health, game speed — all live. Easy, Normal, Hard, Brutal, or your own custom mix. Settings stick between visits.
