I released a portrait co-op tower defense where both lanes share one health pool

Hi — I’m the solo developer of Starvoxel: Defender. The co-op idea is simple: each player controls one portrait lane, but both lanes protect the same health pool, so a weak lane becomes everyone’s problem. Solo mode uses an AI ally.

During a run you summon defenders and merge matching towers while building a squad from 15 defender families. The Android version is released, free, and has no ads.

I’d especially value feedback on whether the shared-health co-op idea sounds clear before you play. This is the short gameplay trailer from the released game:
