Heh, I polluted the area in lvl 7 like crazy. Too many garbage trucks (trying to clear all those crap out). And I can't disable them, so the smog lvl went up to 800. Make a way to demolish/disable them.
Nope, that got fixed. You can't click quit when it is fading anymore.
I googled a bit. Seems there is also a item bug (you can equip weird stuff, and stack items). Just checked, still there.
There is a back to map. See the square thing on the bottom middle area? That's the map.
Also, for training before lvl 2 boss, I suggest the lvl 1 boss (you can redo bosses). Pretty good exp, and items.
I found out something. When you're boarding them, they will not fire their cannons, but you can.
I like waiting till all my cannons are ready, then engage them, and blast them close range. They usually get destroyed within 10 seconds. I lose a few crew, but that's all.
