Spanish 1 ...is there more there more...like Spanish 2
is there more curriculum or does it stop at Spanish 1
I am not sure what you mean by Spanish 2 (as in high school Spanish or college level Spanish), but the skill trees appear to cover most major grammar aspects up to at least an intermediate level. For French all the major, commonly used verb tenses are included plus lots of vocabulary and other aspects of grammar and the Spanish skill tree appears to be similar. The skill trees start quite basic, but build on each new topic at a reasonable pace introducing new vocabulary and grammar aspects along the way.
