Hey! Another fellow Scratch user, how nice. I totally relate to how you feel in terms of this jam.
Although not my first ever jam (My first one was Ludum Dare 52), this was my first Mini jam, and I had an absolute blast with it. I loved looking at other people's games and being able to recognize them on the results screen. It made me feel like I was part of something!
I'm glad you took the time to make Lunar Memory, and I'm hoping you'll make more games in the future! If it's something you genuinely believe that you'd want to do for life, then I'd say go for it.
