I'll admit I'm pretty excited about this BUT I'm a little jaded about how Zep has treated Voxatron, which was meant to be the flagship product. AFAIK, Voxatron was in development and Pico-8 was created as a POC for the Lua scripting to be used in Voxatron. Well Pico-8 turned out to be super popular and almost all dev time seems to go to Pico-8 now, even though it's beyond feature complete. Meanwhile, Voxatron sits apparently stalled and not yet feature complete. You'll see plenty of disheartened users on the vox bbs lamenting this fact.
All 3 projects are SUPER cool. Make no mistake. But adding another project in the mix when Voxatron is still gathering dust doesn't sit right.
