About Danmaku Death: I played it for a half hour. The patterns, framerate, etc seem perfectly decent for a basic danmaku game but I found the controls intolerable. My tablet is second-rate and the touch screen isn't as slick as that of a PS Vita, so I'll borrow a friend's fancy tablet sometime and come back to this.
I think most of the problems are just inherent to capacitive touch screens. Pressing my finger onto the glass means I don't know exactly where my hitbox is or how far I'm moving it - after all, if the angle of my finger changes as I move it across the screen. The ship's speed is also pretty limited, and trying to keep track of that max speed was pretty distracting and counter intuitive. It's not like unlimited movement speed would be hard to design around or anything.
I managed to beat some "Hard" bosses a few times, but "Hell" difficulty was too much with the inaccurate controls.
If this game does support controllers I will be ripping it a new one later. It should be fun, too - some of the bosses are pretty cool. I love the five heads that blow those erratic bubble patterns at you.
About price: If someone sees a game on this list that they think they may be interested in, the current price is easily discovered. It's better to just decide what to play based on the game's qualities, not some external and changeable factor like price. If we add another link, I think it should be a play video. It's not even a big deal in this case. I sure can't afford to import Japanese arcade machines, but smartphone games are cheap.
I've felt this way since I started buying old PC games at thrift shops in elementary school. icycalm's article
On "Values" for "Money" explains the idea perfectly.
About VNS: I like VNs, but I consider them uninteresting as video games (haven't played Phenoix Wright though). We could have a separate list for visual novels if you like, although many have a more complicated installation process than "just download the apk"
Some are proper Android ports, some are exclusives. Many ports are only in Japanese, but the script files of PC translations can be used. Or not. Many are run on a port of ONScripter or a version of VNDS. Basically, that list would be a lot more work
