gets to level 5, if used for level 5 it would go straight for the stairs

now reaches level 6, because it cant make directional decisions properly it dies horribly when a captive explodes [209427]

Now finishes level 6 [0e9526]

Has finished the tower, time for epic mode [061cca]

Finishes Epic Mode with a score of 624 [6bbf8d]
