Hi CazCatra! Thanks for visiting and telling me your thoughts! ^.^- I'm very happy to hear you like ny writing & art-style -and yes! I already started my 2nd project called; Nusantara: Bermuda Triangle. It's a brand new story but set in the same world, albeit with a wider horizon. Fair warning, this one has darker theme than Winged Ones >< It's also going to be A LOT longer so I decided it to be commercial.
The campaign has ended but you can still pre-order via my paypal shop :"3 (see game page for more info ~)
As for your other question:
At first, I use Novelty, it's a great software for beginner programmer because it's more like drag and click rather than typing the program, but sadly, it's still in beta version and I think the creator dropped it u.u
Next, I use Ren'Py and although it's more difficult, it's free and it's like a magic item once you understand its functions x')
And take your time buying it if you want to ~ the completion of Bermuda is still far in the future :"D until then, maybe keep up with the weekly update!
Hope to see you around~
Xoxo,
SweetChiel
