It appears there is yet ANOTHER humble indie bundle...
Most importantly, I noticed Cave Story+ is included, IF you pay more than the average price!
This means it will run on PC, MAC, and Linux. WITHOUT DRM!
And, even without having to have Steam loaded/be online!
To get it, pay more than the average PC price which for me was 4.55$ at the time I got it. It'll be on sale for two weeks.
Here's an official video with more information :
There's something else... the music... is different...
EDIT: I ran into a problem when I first tried to start it; It was missing the dll's : SDL.dll, msvcr100.dll, msvcp100.dll
After getting them and copying them, it ran fine. Also, under compatiblity I checked start 640x480; and it runs great on my PC
