Obviously I'm missing something. I 've found what appears to be a goblin cave entrance (but I can't enter it) and a "Goblin Hideout" which appears to be a bottomless pit I can use to teleport back to the boat (which, by the way, I only got off of by holding my mouse down and spinning it around, since the screen decided to focus on the air above the boat).
Qwandri: Check the planet info before you take off for a planet. It will tell you relative quantities of each mineral available on the plane, as well as which gas is present there.
Great game, but seems that there are some balancing issues that make for a nasty difficulty curve. You either get trampled by the game, or you learn one of the many ways to break it, to survive the later levels. In my case, ice traps + upgraded chargers, plugged liberally into whatever looks like a "return chute" in the map (wherever the heroes travel in the majority of their trips through) makes for a game where, after setting up during round one, I can usually go AFK for the second and third rounds, while the traps slowly whittle down even shielded and armored targets, while healing my shields for ridiculous amounts.
Meh, cool concept, not so sold on the design. Some more variety in the skill "trees" with stronger bonuses to consecutive points spent in the same skill would be nice, allowing you to specialize characters. Right now, getting one point in each skill is all that really seems to matter, since the bonus from additional points is minimal, at best.
Survive 20 turns? Heck, if the game had let me finish moving my heavy during turn 20, I would have killed everything and neutralized every spawn point. Pfft, survive.
Maybe it's just the crummy computer I"m playing on keeping me from getting to the good part of this game, but . . . I really don't get what's so great about this.
Too easy to just wipe out the first wave or two with poison traps (just need one usually if you use advance), then blow the rest away with a couple mist towers in a choke point (with lizard to neutralize air). Great port of the game to a TD, but needs more depth to it.
