Made a co-op merge tower defense where you and a partner share ONE health pool — you hold the bottom lane, they hold the top
Long-time TD player, first time posting my own. Starvoxel: Defender is a co-op merge TD: you and an ally each defend your own lane but share a single health bar, so a leak on either side hurts both of you. Merge Common → Legendary → Evolution, 7 turret families, boss every 5th wave. Solo (AI ally), online co-op, and ranked 20-wave 1v1 PvP with Elo + leaderboards.
The design question I keep chewing on: shared health makes it tense — you can't just turtle your own lane, you have to watch your partner's side too. Curious what this community thinks of shared-HP co-op vs independent lives.
Free on iOS & Android, no ads / no pay-to-win. Happy to answer anything about the merge/evolution curve or PvP balance.
