Actually. The first track, 'Spliffy Boss Battle' is great and could definately fit as a theme for a boss battle. Although the rest is not as good imo. The tracks are very similar to eachother and sometimes gets off-beat. To add quality to all the tracks would be to add one or two more instuments besides bass, drums and guitar. Or at least do something to highligt a theme melody. As I said ealier, theboss battle track is great and does not neccesary need this type of adjustment, however something must be done to minimize repetetive feeling of all songs. Try plan a structure layout for every song including intros, bridges, sticks, outros etc. That'll make composing a whole lot easier and the outcome even better.
Thanks Wartagon. Some good advice there. I agree with you. The other tracks do repeat way too much and are a bit on the simple side. I wrore 'Boss Battle' and 'Ride the Machine' a friend of mine (Toast) wrote the other two. I am in the process of writing some new great tunes for the game and I take your advice into account. Thanks again.
