Sorry for the late reply. I just saw this now, and I apologize for not answering for two weeks :(
And thank you so much! I really appreciate you buying the game again, no idea how did you do it :D That really means a lot to me, knowing that you believe in me and in I Have Known You.
About the bonus code, the code from v4.02 also works for v4.03. If you already entered it in v4.02, then you don’t need to enter it again in this version.
But, there isn’t any new unlocked bonus content in v4.03, because of that I’ll add more than usual in v4.04.
Thank you again for the support, and thank you for checking!
