Please excuse me if I'm talking out of my ass here, I just wanted to give my 2cents about this game, since thats all I can do ;P
So, I really liked the idea of your musical game and I wonder why it's taken till 2018 for a rhythm game where you actually "play the sounds that come out" to exist. I tried the demo, and while its a bit buggy and maybe lacking a bit on the
juicyness department, I really liked it and wanted to buy it and play the other songs.
But the thing is, I think the price is way too high for what it is. Look, I would happily buy it right now
if I wasn't a bit broke at this moment because its you who made it, I like murnatan, I want you to succeed and all that stuff. But I don't see any reason to buy it at $20 for most other people, since there are lots of free similar (sort of) games with more well known songs and many more of those too. I think you would make more money overall if you charged half of that or maybe even less, so more people would buy it and not think too much about it.
Also, I think the song you chose for the demo isn't really that great at showing what the game is all about, since its not that "rythmic" and takes quite a while to get going. I would personally pick the current first one, because: 1) its the first one, so less scrolling needed to see it and 2) sounds a bit more upbeat. But I know this is almost irrelevant cause this is just my personal preference and different people like different things.
Oh, and btw, the demo song on medium dificulty seems to be broken and not play at all =/
Sorry if I sounded too negative, it wasn't my intention at all, I really liked it. I just want it to be successfull, have lots of songs and fund Murnatan
