I've been playing Cave Story since 2004, so I would say I'm pretty much one of the best people to judge this game.
And I've also played every single port of the game, and beaten every single one on every profile given.

This port is dog water. It doesn't have native 16:9 support. It has less content than the Switch version. Which has, local multiplayer, proper widescreen support, and two extra soundtracks. There is no world where the PC version should be worse than the Switch title sharing the same exact name. Sure, the Steam version came out in 2011, so it's using the WiiWare port.

Why not actually use the proper Cave Story+ you already have "made" and give customers the product they deserve.

I love this game to death, and I will die on the hill of the shareware version being the superior version to get on PC (which is really sad).

Others have said it but its true, get the freeware version instead.

One of the most important indie games of all time. It's also available for free but the dev deserves to earn money for their work. Really raised the bar for what kind of game one person could make, and it was free!
