Natsume's translation, while not poor, does leave quite a bit to be desired. The dialogue flows reasonably well, but all of it is exceedingly simplistic and lacks depth. Major grammatical errors are mostly avoided, but spelling errors abound. Natsume does promise that in the final version of the game, all of the typos are corrected from the beta reviewed here, though.
If Natsume really promised that, then they did a very bad job at correcting them =P
