Spoilers/tips: The 170-250 or so water crystal type is coral that is bubbles without grass (basically, since all the undug ground is normally covered with grass, any ground without grass would be corals)
170-250 or so Air fuel would be Ozone, that is invisible, but you are near it when the screen starts getting yellow-ish, the more yellow-ish it gets, the higher the concentration/the closer to the center you get. You get solar cells by standing still on 125/175/225 altitude chests. If the pure water is the same method, then there is either a bug or i'm doing something wrong.
Sorry for double post.
The game is awesome. I like how you get more gold when you get a certain high-score on your previous playthroughs. I beat the final boss in 41 minutes total play(actually, i think this is a bit slow). The trick is that you try to upgrade your health only when you really need it (when you uprade health, you get full hp, so use it as a sort of insta-full hp upgrade), and try to focus on loot & magnet and power. (especially when you get more initial gold).
Also i have a question, is max level 10?(i reached level 9, then on my next playthrough, i heavily invested in loot & magnet (15k upgrade) and the rest to power and fire-rate, and i beat the game, but the upgrade bar filled very slowly, and even though i made 310010 highscore (was about 120000 when i made level 9 i think). This makes me think that max level is 10, and to get it, you need to upgrade the loot & magnet to max and probably get the boost (drone) to help you.
I found about 3 bugs, one might be my computer's fualt though.
1. Sometimes those randomly flying weaponless drones appear stuck in 1 place.
2. After i paused, did something on the computer and then continued, the game was as if in slow motion(which made it a bit easier), but it seemed that it didn't affect the money's lifetime(sometimes they faded rather fast, in those chase parts), after a little it fixed itself.
3. The boss with the 4 turrets around it. When i destroyed all 4 turrets, my weapons targeted bottom right of the boss(and thus my full boosted weapon's higher central damage missed almost all of the time). I think it is thinking the boss is located where his bottom right turret was.
I'm not sure if the downloadable version is up-to-date, but the "Three Towers" level puts orange and red army, but not blue(the player), maybe the orange is supposed to be blue???
i am not sure if this has been answered, but nexus226, you can run over buildings you destroyed, it's just that they have to be DESTROYED(not just take out the enemy, but also destroy the building itself).
omg, i have no idea why they don't work for you, but minelayer and healing work perfectly, and healing is very important, especially once you get it to level 3, 0.7 cooldown on healing with a good heal(well, it's 1.0 cooldown if you haven't upgraded them). It's very much worth playing, the only bug that i've found so far is that the multi-laser hits 1 air at a time instead of 1-2-3-4-5, and another thing, you need to be able to sellect what to build and what not.
You can shoot, just press space and buy the weapons, you can destroy your enemies, you just have to shoot a lot(2-3 passes(go top-left/right, then when they are near you, just slowly go bottom, while shooting them(you can't miss when you use this tactic))
Yeah, i quit from the second mission too, i almost finished, but then when i am at 30-40% hp and it says taht i am dead. Also i shot takes 30% of your hp
face612, in the research screen, that is where the recipes that you discovered, but haven't made yet. Then you just need to go to the cargo list, choose the item you want and then press craft.
Oh and to finish the game, play the last video(maybe you need to play all the videos, i don't know, but in the last video you find the coordinates of the planet from which the escape pods were launched(the things you find with the elevator beam) 2500+- years ago, go to that planet(it's a red painted largest circle possible(like a normal planet, but red coloured), that is probably Earth, because when you go there it says that the Moon is shattered, well...you will find it yourself.
Oh and from what the end video says, there should be a sequel, where the robot discovers/invents/something the equipment that he needs to do Aerial/Underwater(the planet is a Water world(maybe the continents sank/where destroyed)(Well... Earth is sort-of a Water world(2/3))
Goldenfire, are you that lazy to press and hold S or the down arrow button on the keyboard? It cancels/reverses the effect of the elevator beam=>you stay on the ground and refuel/repair.

it increases faster on fast mode, but it wasnt shown in the worker-card. I changed that now.
