Is Insane Mode way too hard and you (somehow) can't get past the first level? Well... I found a neat little glitch that lets you get a biiiit more money so YOU can get a head start. So, here it is. On the first level, don't click "I already know how to play" Instead, get a few troops-around 4-and THEN click "I already know how to play". you will then get a bit of extra money and you can get maybe 7/8 troops out of it.
Why doesn't it give you money if you click "I already know how to play" in the start? I guess this is because the tutorial thinks you won't click it halfway through. And because the game gives you the money you SHOULD'VE earned you get that extra amount of money.
Anyway, I hoped this helped some people. :)
If anyone needs help with other levels, please, PM me on the Stick Forum.
