"Come On! Dragons arrives on DSiWare with the promise of delivering a combination of tower defence and arrow firing action, much like its predecessor Come On! Heroes. Like the original title it succeeds to some degree, but its positives are weighed down by some disappointing flaws, meaning that it's not as hot as the title may suggest.
While there is a basic story — dragons are invading, you must save the world — it's not particularly significant to the game at hand. There are changes in environment that suggest you're defending a kingdom, all perfectly serviceable, but the plot is an irrelevance. We wouldn't complain if this campaign wasn't called "Story Mode", and it seems that this fantasy setting would have been well served by a tale of fantasy.", writes NintendoLife.
