I'm one map behind, but playing as Brood of Bane was excellent! My only suggestion would be to improve the interface when building units as each click to morph an advanced unit takes you one interface back if you have multiple Banelings selected.
Hi there, I've got about 6 hours of feedback on my channel for this series, but I will oblige your feedback thread here too.
This campaign is one of my absolute favorites and worth a play due to the tone and uniqueness of the Marauder faction. Huge shoutouts to Marauding and The Mechanic specifically for being some of the best, most interesting, and fun individual maps I've played as well. That 'AHA!' moment in The Mechanic when I grasped that it was Metroidvania was one of the happiest moments I've had playing a custom map.
Nitpicky issues I had were with the end of Mission 2 being very challenging and the map is large enough that reinforcing after a first failed attack on Bob is semi-frustrating. Mission 3 and having to destroy literally everything, perhaps consider adding indicators on the minimap when there are <10 or <5 units/structures remaining. Also, the Zerg canyon sections were fun, but my clicking finger was exhausted! I found Rising Tide to be so challenging that I couldn't make it past about 10 minutes, though maybe I couldn't quite grasp the way it was intended to be played.
I recently played the new Mission 10 and was happy to see you've retained the exact same style as the original maps - I have a video of it coming on Friday.
