If you loved Project A-Ko, try Dragon's Heaven
A bridge between a film you've already seen and one most people haven't. Here's what they share, and what the second one does that the first one doesn't.
What they share
Theyboth carry the unhinged mood tag, and they sit in Action / Animation / Science Fiction territory. If that's the register that drew you to Project A-Ko, the second film will land in a comparable space — through a different lens.

What Dragon's Heaven is
You awaken in a mech, a millennium after a war. The robot uprising still plagues Brazil. But now you have a human partner. His plan is to find your old nemesis and end this conflict once and for all. Kobayashi's film is an obscure and frenetic OVA with designs cribbed from Moebius.
