Hi Luupuxall!
I understand change can be disappointing. It took me 5 months of dedicated work to make vertical edition for M3 for kickstarter backers. I can't do that again for miru when we've already moved on to the new format and the game series is complete. It was not a minor update, alot of the structure of miru changed and was better explained. (i get a lot less rule questions now than before anyways)
We do offer a pretty affordable printed version of MIRU. And the digital edition is printable and can be made into a nice book if printed on tabloid size paper. (could be at home or at fedex) It also works just printed on Letter and stapled in a corner. The digital edition is not meant to replace our hard copy, just supplement for more portable reading and for folks to try the game out at a more affordable price.
