Thanks for playing!
Are the two beeps that you're talking about the ones that only play on certain levels? Those are actually supposed to be the laser sounds. I wrote them in the same LMMS file as the music but exported them as separate tracks so that they would sync up with the laser movements, but would only play if there were lasers present. I probably should have just made them sound effects, though, because they desync a lot more often than they should.
The development of the composition is actually pretty interesting. If you listen closely, you may notice that there's two different sets of lead instruments. Some of the instruments only play on the first half of every measure (e.g. the analog bell and the kick drum) and some of the instruments only play on the second half of every measure (e.g. the analog times synth and the snare drum). This was done to create a distinct divide between the measures (although whether or not the divide is noticeable is a different story).
It's more obvious if you're wearing headphones, because the "player" instruments are panned more heavily to the left, and the "obstacle" instruments are panned more heavily to the right. Try playing with headphones if you haven't already!
