Grand Chase as a title is a little off-puting.
Hmmm, stumbled across this little loop and I must say, I really quite liked it. Very, very chilled, which is a good thing. It's definitely more ambient to me than trance, but I feel it would be well suited in a video game soundtrack more than anything else (in it's current form). I don't have a problem with the repetitiveness seeing as it's a loop (in fact I've had it playing during the composing of this review and it hasn't gotten annoying or old in any way), but I suppose you could branch out and make a full blown song out of it. Could be cool. I would be inclined though, to be careful when adding more and more to a track and trying to create diversity. Sometimes, the original effect can be lost.
By the way, Liquidfire666 mentioned that he got a Bomberman64 feel out of this track and I have to agree, though I also don't know why exactly. Something to do with the vibe of it.
Keep up the good work anyhow.
