I'm sorry to say that Pixel Pup will not be coming out for the e-Reader due to manufacturing challenges.
Instead we are working on a larger, much more polished and just plain better version of Pixel Pup as a standard GBA game. All of the puzzles originally planned for the e-Reader version will be in the GBA version. On top of that, we are shooting for more puzzles, more features and more modes.
We will be sharing more about GBA Pixel Pup as it progresses, primarily on Bluesky
My remaining stock of Series One is all that will be available. The US version in particular is getting low in stock, so if you want a pack you might want to grab one soon.
That's a good question :) The very quick version is insurmountable manufacturing issues. Basically the cards don't scan well enough. I'll tell the long version soon, I'm still collecting on that and figuring out how to explain it all.
I just wanted to rip the band aid on the bad news and get it out there right away. I'll share more and explain all the details in the coming weeks.
