Impossible badges are meant to be really challenging. This is not so challenging, but really really time consuming. Hence "Endurance Badge". Though, yeah, this should be like a "Super Endurance Badge" or something.
On level one look at the little seeds on the right. Every time there are 6, send out a column. I got 216% skill. It doesn't even matter if the tar bugs get into the water.
The red circles do not hurt you. I was avoiding them the first time. Also, to be the most annoying game ever, you'd have to make the controls stay the same when it rotates (W would move you right for example)
Add Kong to your safe sites list if your controls stick. Tools-Internet Options-Security-Sites. Make sure the box at the bottom is unchecked. Alternatively, switch browsers. IE is the only one that does it.
If your controls are sticking, (you move in some direction, or do something repetitive), add Kongregate to your "Safe Sites" list. Tools-Internet Options-Security-Sites. Make sure the thing is unchecked at the bottom of the "Sites" box. That or get a different browser, IE is the only one that seems to do it.
Final level on epic, as soon as your heroes spawn hit Assault. Use maxed shield as soon as the boss comes out, and keep using shield when it counts down to 2 seconds (above the minimap) Easy peasy
Simple, complex-looking puzzles with a simple solution. Most of the hard levels are about timing, waiting a second here, or going as fast as you can. I like it, favorited and 5/5
