Thank you! I am glad you like the sound choices, it's sort of inspired by music that use "nostalgic percussions" such as children's toys or soda cans. I believe "Mabe Village" from the Link's Awakening remake also slightly snuck it's way in here too (and probably the Mother 3 soundtrack also)

For all the samples I've used in the beginning: The wind-up sound and camera flash are some royalty free samples I found on Pixabay! The bubble, beginning pads, marimba and organ all come from Mother 3 soundfonts(There's a SFX one and a general one if you plan downloading them). The main lead I created in 3osc using a sine and triangle wave both with slight detuning and phase offset, very slight attack, and vibrato. Its pitch also jumps up very quickly similar to an 808 kick. And lastly, the pluck that repeats the main melody, is a sytrus preset (fittingly) called "Child's toy". It came from an asset pack simply called "700 free sytrus presets"!

Thank you, your words are very kind!
