Level 1:Click,click,click,...
Level 2:No comment,you should figure it out yourself
Level 3:Too easy to give any hints
Level 4:Beware the trap,release the other lems in time and keep a builder at the end to build in the exit.
Level 5:You obviously can't use the same method you're used to do...
Level 6:Try to find the best way to control the crowd with your spare builders.Building at an edge of a gap will certainly help you.
Level 7:Can be fun to watch and 77% is the most I achieved...I'm sure if you're lucky you can get over the 80%...
Level 8:Ah,my favorite level...you can't bomb the lower parts of the trees,so keep your bombers high enough...
Level 9:No hints needed,solution is obvious but somewhat tricky to do.
Level 10:Use 3 builders near the entrance to contain the crowd...no further comments :)
