Only one thing: will you continue to develop the app? I really like the idea, so I want to help testing the app, for example I've found 1 bug and I have 2 suggestions
(sorry for the late reply, but I've the memory of the phone full and I can't receive e-mail on it xD)
On organya for Android there was a bug that some song doesn't play, I resolved reinstalling the app.
Also, if the app could play the music in background would be great
P.s. I've seen you come from Italy
Yeah i saw that bug it looks like i should add a cache clearing function because that's just a cache problem loading too many songs at a time (just resetting the app helps aswell)
And for cave story port i used an app found on playatore called GamePad that simulate a gamepad
And as for the port i've made a full animated player now (now it has every player animation so it doesn't has a player walking in midair bug nor anymore) and I'm working right now on shoting system for polar star, oh yeah i've added a new kazuma's cutscene too
