Sisters Royale for Switch

This year, Alfa System had made a comeback with a new shmup on Switch as part of celebrating the company's 30th anniversary. The game is a whole lot like Castle of Shikigami series but with some differences. Firstly, the bosses are actually other playable characters including the man the main characters are competing for. Secondly, there doesn't seem to be 2-player support along with other modern presentation features like online leaderboards. Third, the characters are on the ground like Cave's Guwange and some NES Hudson Soft shmup where you can move around on the ground and jump on the platform. Lastly, there's no voice acting whatsoever. So, the presentation is akin to an indie computer game or perhaps an arcade game of the early 2000s.
Story concept-wise the 5 playable characters are competing for a man for some reason like date for instance. It may have been suited for fighting games but then, the stages are not in random order no matter which character you play as and the final boss takes place in the final stage as well. The second flaw is the lack of voice acting, online leaderboard and 2-player support. At least, you can switch to Vertical Mode and customize the controls unlike the Zerodiv ports of Psikyo games on Switch where there doesn't seem to be a way to customize the controls. Third flaw is how the explosions are programmed improperly like they tend to disappear out of the blue over whichever character you're playing as along with the shots you're using at the enemies.
One thing to remember is that when it comes to a fighting game about fighters competing for a love interest, the tournament is assumed to be a trap. You're already better off finding girlfriend/boyfriend the other way but what if multiple people have the same interest as you in that particular person? Also, the game's subtitle is quite wacky at best and who knows if that man is either the crush of those 5 sisters or maybe their brother? Things went on for like 1000 years according to the game's story and the game's ending takes place a year later but again, I can barely read the story so I barely know what's going on. Lastly, this isn't like the other games that have the word, Battle Royale in the game's title. The game could make more sense as a game of other game genre but shmup though, maybe a versus shmup may make closer sense like SNK's Twinkle Star Sprites.
As of this writing, the game was recently released in Japan digitally on Switch like last week or something. It's been a long time since the third Castle of Shikigami game and there was like no momentum whatsoever for the series sometime after the third game and the recent releases of the original Castle of Shikigami on IOS & Steam regained the momentum like a little bit as that time, people were already into other modern shmup games, like Cave shmup games ported to consoles, mobile and Steam, Crimzon Clover which is one badass Cave-style indie game which can be bought on GOG and Steam, Raiden V and Caladrius by Moss and of course other indie shmup games that have the professional game platform releases like Exception, Trouble Witches, Resogun, Super Stardust, etc.
Like Success Corporation, Alfa System worked on other games that have more momentum although Success went in a different direction with a bunch of HTML5 web browser games ranging from casual games to games with similar replay value as modern mobile games.

Shikigami No Shiro/Castle of Shikigami on Steam

The external developers that made the IOS version two years ago ported the game to Steam this year but compared to IOS version which is decent in conversion as I saw the gameplay videos, the Steam version is a DIFFERENT DISASTER!
Presentation-wise, there isn't so much support for external controllers and the control customization isn't quite good. Not to mention that the conversion is bound to bring damage to people's ears during the boss destruction sequence from the way it sounds when compared to the arcade version. The sound effects are messed up, the glow and ring effects are messed up and it should be simple enough to base the previous PC release which obviously uses 640X480 resolution with new HUD. Another thing that's messed up is the Stage Clear text which obviously doesn't have the glow effect at all when compared to the previous releases. The last problem is the port's presentation in which the game uses HD resolutions for some reason instead of basing the previous PC release like Raiden III on Steam did. This causes the in-game graphics to be much more blurry than ever and there's no reason to enhance them like making them sharper or some kind since the game originally came out for the G-NET system in the arcades. XIIStag on Steam and Xbox 360 is more or less decent when it comes to conversion but it misses some of the graphical effects as a result. Maybe they are too hard to emulate or some kind.
Speaking of XIIStag, there's also XIIStag Limited on PC which uses 3D objects instead of 2D sprites but the game still looks exactly identical.
The plus side, you do get the decent translation and original voice acting as well as proper in-game presentation that matches the arcade original. The western Playstation 2 release known as Mobile Light Force 2 surely butches the translation, voice acting, scripts, presentation and various parts of game publishing like the title screen has nothing to do with the actual game for instance. So, both the Steam and western Playstation 2 releases are kind of mediocre at best and finding other versions released in Japan will be extremely tough. The IOS version is decent at best from what I saw but it's not the same for the Steam version. The sequel already improves things a little in the west with proper game title and title screen.

Shikigami No Shiro for IOS

From what we saw, the game for the IOS can be suited for Iphone 4 and above as the wallpaper doesn't even full up the entire widescreen for Iphone 5 and 6 but on the Ipad, it is completely fine and the game looks similar to other shmup games ported from the arcades to the IOS. The gameplay resolution is on the top center of course with the button layout looking quite similar. However, as the game is released like this year, I may probably assume that the game works for Iphone 5 onwards like we may be out of luck. Not to mention that the momentum for this series is completely dried out after Shikigami No Shiro III and Alfa System is already developing something else ever since the past. It may be the same for Skonec which is still around and we had discovered a Dance Central-like game developed by them. Also, the in-game buttons are kind of confusing for some reason as they completely full of text instead of picture icons and they're in Japanese.
