It's that I had bought various IOS arcade games like Deathsmiles, Dodonpachi Daioujou, Miku Flick 2, Darius Burst SP, Mushihimesama, Rayforce and Raystorm just because they were like released 3-4 years ago. Besides those, there were other games like Mushihimesama Bug Panic and Dodonpachi Daifukkatsu which I bought for the IOS. Perhaps, I had never played them before until I bought them.
Gladly, there are superior videos of this version of the game with all stages shown but be warned, there may be serious spoilers taking place in the final stage at later difficulties in the Smartphone Mode. Also, someone on YouTube has revealed the entire soundtrack for the Smartphone Mode so that people can know what it sounds like for that mode. In addition, I might have arranged some of the songs from that game mode.
