I quite enjoyed the third track and can see myself fighting a boss while it plays. For the first two tracks, I thought there were some pretty cool ideas, but they struggled a little to find a "home". I think a big part of composition is finding a good balance between tension and release, and while the perfect balance is totally a subjective thing, I felt like you built up a lot of tension without releasing it very often. I think having a more clear home chord could help here.
Another thing I quite liked was the choice of instrumentation, well done! The little bell sounds were very cute :)
