I've never really played Cave shooters despite their acclaim. They just seemed way too hardcore for me, at least based on the crazy 1cc Youtube videos, but out of curiosity I picked up the iPhone version of Espgaluda II. It was only 9 bucks, so I gave it a shot. Man, what a game. Definitely, one of the the better iPhone games. I played and beat easy modes, but it was still very fun. Some highlights:
-The game is challenging, but your hitbox is actually very small compared to your sprite, so the waves of bullets are actually avoidable.
-The game provides you with tools to avoid waves of bullets, so there's some strategy involved. It's also much more forgiving than Ikagura, a game that soured my on the genre.
-The music is fantastic.
So, I might look into getting proper console versions of these games. I know DeathSmiles just came out; I also know the Japanese 360 has gotten a bulk of the games. What other Cave shooters are available for a North American region 360?
