That used to happen to me a lot, which is why I now refuse to write anything directly on a web page xD I ramble too much, and it would often get lost, haha. I always write my replies and stuff up in a separate note now where I know I can save them, haha.
The $2 isn't a purchase price anyways, it's just to help the development of the game to fund voice acting and stuff since I can't afford it myself as I don't have money either x3 So if you want a key, feel free to drop me an email to: melancholicmarionette@gmail.com
A lot will be changing compared to how the game is now though once the update is out since I've revamped all the old stuff and added a lot more choices so that players have more control over MC's personality and stuff :3
