You have some interesting ideas here! Thanks for sharing. It sounds like you want to know if your music is "good enough" to be placed in a game, right? Well, that's a hard question to answer. Mainly because there are so many kinds of games out there and video game scores vary greatly. Listening to your tracks I see plenty of interesting ideas that could work really well in a video game realm. My advice - pay the $7 it costs to post as an indie and see what kind of response you get. The ad would be live for 45 days and $7 is not a huge investment.
Sure, we (all the audio nerdz in this forum) could debate and discuss all day long about what makes good audio for games but what really matters to you, to all of us, is if people are willing to purchase our music for use in games. And there's only way to find out!
Your stuff is interesting and different and that's a great start. Go get em!
Thanks,
Nate
