im giving this 5/5 no doubt about it ... good music, nice scene setting, and for anyone who has suffered through 'this is the only level' badge, im sure you are happy to see this lil blue buddy again
forget about noob guides. to truly break above level 160, your maze should consist of machine guns (for mazing), heavy cannons (because got blast radius - most creeps end up in traffic jam later anyway), and missile turret (about 50% of your screen). you need to maze 2 paths to your based, block off 2nd one with a wall block. when the creeps almost reach your based on 1st path, sell off the block, then plug a new block to your 1st path. now the creeps will walk backwards and go 2nd path. repeat as necessary, and no ground units will every touch you. for air, you need an insanely lots of fully upgraded turret, and you will probably start using EMP blast on them after level 150 for the turrets to take them out. all other towers are useless (pulse, flak, laser, plasma, etc). bomb and nukes are also useless.
