The Japanese indie / doujin fighting game scene isn’t anything new or unheard of. While no Guilty Gear or BlazBlue in popularity, there are titles like Melty Blood that have gained at least some following. Inaho Town: Dynamite Bomb!! isn’t the most obscure doujin fighter either, yet it also lacks much fanfare. I generally go into doujin games expecting little, but found the title to be surprisingly accessible and competent for the genre.
Most Japanese indie games haven’t been prevalent in the industry over the last decade. A growing Steam presence is starting to bring many of these games to light, but plenty have yet to make the transition. Until recently, they were almost exclusively created for low-print runs at Japanese conventions or, in the cases of digital distribution, shoved in the obscure corners of the internet. This includes Aqua Cube, a cute puzzle platformer released for PC back in 2008.
