Galak-Z has gone through some changes since we first heard about it. The space shooter from 17-bit Studios (Skulls of the Shogun) has jumped on the roguelike train. I mean space train. Damn. I messed that up.
I messed up plenty playing Galak-Z as well. It took a while just to unlearn Luftrausers flying controls, though that constant fear from imminent danger remains from a multitude of enemies. Peons, Gundam-esque mecha, space spiders. 17-bit's Jake Kazdal explains that Galak-Z has the best AI around.
It's certainly aggressive, with a little bit of wiliness.
