It's the same as 'continuously' but not the same as 'continually'.
'Continually' is used for things that happen often but they stop and start -for example 'He was continually interrupting me.' - he interrupted me again and again.
'Continuously' is used to mean 'without interruption'.
You could also say 'They worked non-stop to make a handsome snowman.'
