I love using the spike factory/Ice tower combo. These work well together. Also the gluemonkey helps but it needs the ultimate upgrade.

The game keeps glitching every time the spike factory is added as it tries to add an empty icon which then becomes the spike factory which I already have, which causes the start round button to never show, and is instead shown as the fast forward button, which does not start the next round.
