It was Secret Switch Game-appaloosa on the Japanese eShop this Wednesday. Here is what came out (I am skipping a few less eventful releases) on the same day:
SNK Vs. Capcom Card Fighters Clash
One of the greatest digital card games ever, originally released on an obscure hardware nobody thought would make an official commercial comeback, involving two different IP holders, and the re-release includes the two versions in a single purchase. Also available overseas.
Arcade Archives GunNail
A vertical screen-oriented, FlipGrip-friendly late era NMK flashy shoot’em up that competed with Batsugun in the arcades in 1993. Also available overseas within a few hours.
G-mode Archives Kamura 〜Kamigami to Chigirishimono〜
A seemingly inspired Japanesque RPG, originally released on i-mode with a battle system heavily influenced by Grandia!
VazialSaga: Guminka Senryaku XX
An upgraded port of StudioGIW’s dōjin game VazialSaga, a simple 4X focussed on diplomacy, politics and treason in a feudal pseudo-China. Weighs a glorious 60 megabytes in total. (See a previous post in this thread for more on StudioGIW’s works.)
A cross between Tower Defense and Slay the Spire with lewd drawings of princesses that get stripped of their clothes when they lose.
Tsukūru Series Game Battle Tycoon
(Unrelated to Battle Tycoon / Flash Hiders.) A mix between a fighting game and a Bishi Bashi-style variety party game developed entirely on the amateur game development engine Pixel Game Maker MV by Retsuzen of Crazy Power Disc fame!
