I'm so glad you told me about this because this is possibly the best thing I've ever been graced with, it's like my birthday and christmas came early.
I already loved Jack (who, has had an incredibly long-lasting impact on me even after the game jam I met him in had long ended) but there is genuinely no other way I would have wanted to see him again.
TL:DR; THIS IS THE BEST THING EVER I LOVE THEM TO BITS!!!! (if fanart were to ever be produced.. how should I send it to you? because I can't not draw these two. I need to.)
More on the game itself: I'm so charmed by how fun you made this! I've always been more into visual novels that take a bigger advantage on them being games and being a "visual" novel rather than just being novels with moving pictures. Not only was I very much enamored by the characters you created, but also just had lots of fun with the visuals of the game, the grammar fixing minigame, the sounds as well!
I love your games and your characters big time man!! :D
(I wish you the greatest luck on the game jam and I hope you win!!)
