Isn't it a bit much? :)
If I had your time I would focus on polishing the game and maybe add more features, with only a few levels to showcase the game. Quality over quantity.
but it will have its own quality too.
fun levels, related to things. or just harder ones. i have too much ideas for levels so im just putting it all in one…
it will be even divided in sections of levels…
(somewhen i needed to make something bigger than ≈ 20 levels…)
and even a little spoiler:
