so catchy, what an uplifting and cute vibe : ) there's so many snail's house-isms in here (particularly the melodic bits), which i guess based on the tags is extremely deliberate, haha. you did great at replicating that style, and it fits the character + style of the artwork you chose nicely.
frankly this seems spotless to me, the production is clean, the song shifts gears in the right places, and the writing is fluid. i don't have a lot to note here - maybe it would've been cool to see a more adventurous solo in the final big section in the last minute of the song instead of mostly repeating, but i don't really think the song suffers for it; it would just be an option to dial the excitement up one extra notch, maybe. it's so solid as-is; awesome job!
