Actually, Celeste was not top of mind when starting this but others have noted the similarity, and I can see it myself and I also started replaying Celeste yesterday because of it :D
The idea for the game is actually a very boiled down version of something I have an idea for, which would be more of a metroidvania where your abilities and health and so on would all require the same type of resource. So you could have your double-jump enabled, but maybe you're not able to take a single hit from enemies or something along those lines. When the theme was robots, I felt like we could make something on that same idea but very slimmed down - and turn it from a metroidvania to a platformer, having the pods/pickups be single use.
And you are correct with the music and SFX! The pickup sound was meant to help a bit with timing of jumps and dashes, and it's in the same scale as the music to fit in together. Had even grander plans of making the music modular and react to different things but after 8 hours of not getting the music to work and jump around different patterns I scrapped it as there was a lot more things to do.
