Ristar 2 (Remade Demo)

Hey man, this is a really great and interesting project, I've been wanting to make a sequel like this one for a while. I was wondering if you knew what tools or programs that would be needed in order to make something such as this. Thanks!
looking forward to seeing more about this.

game feels very close to original Ristar, minus a few things that could be adjusted. but i believe the author knows what he's doing.
