Im going to write a detailed guide, and it is going to be sliglty an overtrained based one.If you overtrain, the levels will be a breeze.
Ok, so first, beat level 1. Ignore the blue thing at the top, as you will not need it until you get a skill. Save, and go to upgrade. Buy the comet skill. If you have enough, upgrade gobins. If not, repeat level 1. Make sure to equipt the comet skill too. Continue on to level 2 as many times as needed until you have 5000. Buy popo the dwarf. Now, go continue on to level 3. Buy madbull after level 3. Continue to level 4. Get orangutang as soon as you can. Continue to level 5. Upgrade your viegraff, and if you can, get the phantom ghost. Once you have that, continue to level 6. If you need small amounts of cash in shorter times, beat an earlier level. Buy rain of arrow and castle. Keep completing level 6 till you have might guardian. Or if your closer to it, do something like level 3. I will continue this guide some time in the future. + if it helped.
