The map expands to the right once you find a certain area. I think that's what you're missing.
The new miner is way more balanced than the MCUs were in traditional starcraft mining. In the traditional style, they mined so fast that you'd have a surplus of resources on every map they were in. It's all due to the fact that they have instant movement acceleration, unlike SCVs, Drones, and Probes. In any case, the new system is supposed to emulate Command and Conquer. I've been slowly transitioning to it with all 3 parts of Kaboom Baby. You maaaay or may not have noticed, it's not extremely obvious.
That little bitch was out of range of my monothumper army... I got rekt on the first attack, i let them clear all my army and two minutes after i kicked his giant ass with mah roborauders
The jumping buildings is an interesting idea, i lifted the club near to my army to can buff them, but i also could jump towers of power so to don't have to make Motivators or add the turrets as extra army... A little touch that add a lot of interesting ideas...
The terrain is ok, even if it's hard to understand that you are under water, you should touch the gravity imho, so the corpses flies up, but i don't remember where section of datas contains it... Maybe also adding more fishes and sharks, i don't know...
An example of an underwater map that looks more like a real underwater world (i am NOT saying that your map is bad, but that this one is better)
I checked better the megascvs and they are better of the MCUs now that i watch them better, even if they take forver to be builded
I would complain about difficulty but it was a tutorial mission as you said so... Ok...
Queen of Bane has a major bug imho, the giant swarm host is not on your F2 hotkey, so i often lose her around, other than that was really fun with fresh mechanics, congratz, baneling race is retarded and awesome like the marauders one
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.
As far as I know, thats just how it is when using a morph ability with a command card after the first. It could be fixed by putting everything on the first card, but theres not enough space for them and the standard buttons.
