I would just point out that binding keys to W and ctrl could cause the browser tab to close (ctrl + w in google chrome, dunno with other browsers), su i recommend use X for the boost
1st km: ~37s -> avg 97 km/h
2nd km: ~31s -> avg 116km/h
3rd km: ~29s -> avg 124km/h
4th km: ~28s -> avg 128km/h
5th km: ~27s -> avg 133km/h
and so on, it seems to me that it stabilizes taking 1 second less for each km afterward, so the 15th for the badge will take about 17s at 211km/h and the 20th is done in 12s at 300km/h...
pro tip: many of you might have noticed that numbers on the side turn grey when the corresponding block is placed in the right position and all the squares closer to a side are filled correctly
1/5, you should be able to sell units mid wave, a wave should be supposed to end after a certain number of units and not last forever if you're unable to harm it and a easy badge requesting poison to finish enemies shouldn't be requested when in an early wave you meet enemies resistent to poison
It should be clarified the way you make points in time attack: it should be written there "each second you gain (age of civilization + sum of level of nexuses) point", because with what there's now i thought it was calculated after game, so you have 600*(age + nexuses) points and fail to conquer the badge...
It's just me or, while the badge tooltip states easy badge is earned at killing 100 enemies, the badge is given after killing 1000 enemies? I reached the goal in level 2-3, part 1, so it's more likely i killed 100 or 1000 enemies? Am i mistaken, or is the tooltip wrong?
I missed a place by 21227km, beat that if you are able (it's not possible to miss by more than 20037 km or so, since this is the distance of 2 symmetrical point on the equator)
