I've pretty much 100%'d the steam version. Here's my gripes with it:
>QoL features from Switch version still not added despite being promised years ago.
>Beating any of the challenge modes will crash the game
>Original Graphics option does nothing on Curly Story or any of the challenge modes
>Has one of the worst excuses for a "hard mode" i've ever seen in a game
>Some achievements are misleading (Wind Fortress say you need to beat it in 4:00 but it's actually 2:00.)
>With Wind Fortress being the sole exception, none of the new features are worthwile enough to justify adding a price tag
Still prefer the original overall.
