The only thing that makes the "impossible" badge that hard is level "e". I have passed all the other levels with the keyboard and need to finish "e" in about 60 sec, but I can not get past the first obstacle.
Congratulations! You just won the Beyond Clicking Badge and 30 points! LEVEL 70 IS INSANE! You are dealing with lots of "areas" with only some of the more basic power-ups.
To all those who are having trouble, KILL THE YELLOW BALLS FIRST! As soon as you can keep up with the furthest out balls and do meaningful damage to them, KILL THEM! Let your allies deal with the little guys that go after your base. Do this fast enough and you don't have to worry so much about the enemy upgrading. And you can't hurt the red one until ALL the yellow are dead.
I would like to be rewarded for surviving a long time on the same level with waves that take one second longer to appear every, or every-other, time. This would not change the basic game play like the "colors stay gone" or "same color pucks connect no matter what" suggestions but would help the people who have the skill to finish yet keep making small mistakes.
lasted till day 32. EVERY WAVE IS A BOSS WAVE! I lost exactly 1 unit before wave 31 (and no walls/towers) but 31 killed a tower and I could not repair enough to survive 32. 3/5 for good, but nearly impossible.
This should be in the "longest lasting game" challenge. It certainly takes long enough just to get to floor 25, let alone 50 or 100. Too bad it was submitted months ago.
4/5 nice layout, but gets boring and there are a couple of things that could be improved: make the grid-lines a little easier to see and have a "see-through shapes" option. The challenge should be a bit more on the "how" then the "where."
2/5 Was not remotely challenging until day 7 and completely repetitive around day 17 (played a bit further, but stopped before day 20 when no more upgrades appeared).
2 small things that can make this more fun fairly easily: have the rate of appearances increase at a slower rate and bring the "curve balls" into play at an easier difficulty. (I barely get to see/appreciate them if they do not appear until 1200.)
Good first game. Could use some better graphics, wall mechanics (the guy is often just above/below the ground, not on), and a less pixel-perfect jump on lvl 17 (going from the platform on the left to the top set of platforms). 4/5
wow, that was all 54 lvls. Wish the overall difficulty (not just the gold metal times) got harder and the mini-guinea pig maker showed up a couple more times, but not bad.
dang it. Managed to keep Burning Hell through 3 hits, collided with a bigger rock, and suddenly I was at 0 mass. >\ Anyone actually finish with Burning Hell? Good hard/impossible badge?
