Impressive that you did these tracks while still getting familiar with the DAW.
Escape - This sounds pretty ominous. I quite like those blippey sounds. They give this track an almost outer space feeling. I guess they refer to the protagonist being from there?
Boss Battle - The boss battle is really cool. I also find the inclusion of the vocals a really cool touch. "It's tiiiiiime for a boss battleeeeeee" and "There's a plane out there!". Brilliant! :D.
Ending Cutscene - The blips are back. It did sound like a finale.
My fav was the boss battle. I like the excitement it conveys!
