Hi! I just released Chain Keep, a free tower defense you play in the browser, on PC or phone.
Towers of the same kind placed side by side link and boost each other, and three or more in a group form a chain with a perk: bouncing bolts, bigger cannon blasts, deeper frost, stronger lances. Hold your castle through a campaign of 10 levels with 20 waves each.
- Link and chain bonuses shown right on the board
- New enemies and four bosses across the campaign
- Permanent keep upgrades from every run, won or lost
- Tower specialisations, stars per level, endless mode
- Tutorial on the first level; keeps running when you switch tabs

It is meant to be hard. Which level stopped you, and which chain did you build?
