Not very skilled? Wtf are you kidding me? These sound fantastic!
StageComplete: BONUS!
Stage 1: Sounds like it'd be great for a 2d/3d platformer or something like it. It really grooves and has great forward momentum. Cool breakdown too with those rapidfire synths.
GameOver: Yeah, sounds perfect for the job.
Stage 2: Sounds like the stakes are high now. Sounds like one of those tunes for a level where every mistake means restarting. For some reason, I'm picturing a level like in battletoads, where you have to dodge things that fly at you at a razor pace. Love the energy in this. It's only with a tune like this that replaying difficult levels becomes bearable.
Great job! Stage 1/2 are going on my rotation :D
