@Potbelly, sorry, but I've closed the development. It's "11+" because it's a part of a PC, not a calculator, making it "1+1" would take 1 more slot of memory.

All the developments on 8bit model are closed now too. I'm finishing the school this year, no spare time you know. Also, 8bit method I've thought about is so hard to make in PT that it just blown my brain.

I'll 90% possibility newer return to Powder Toy. Sorry me.
