Thank you for the kind words! <3 It sounds like it was probably around v0.15 or before we swapped to Ren'py for our game engine. We wanted to take what content existed before, but improve it and introduce it in a better paced way for the story and episode format. So that's technically the downside, is that we've been adding new content mixed with existing content and it's a bit slow in that sense.
But we'll be pretty much caught up on most of the existing content and it won't be long before there's more overall content than long before the Ren'py swap. :P We hope as the releases continue, it'll surprise many for what's still to come for MA!
