Very nice game! Firstly I love the graphics, cute and simple, I really liked it. The UI was also nice and clean, and easy to understand.
The tutorial could have probably been sped up a little bit BUT I like that you added one in the first place, most game jam games suffer because they didn't have an explanation.
I also really liked the audio, it felt like i was playing a kid's educational game again and it reminded me of primary school/highschool haha.
Being able to explore the level from the start would be nice, but I also understand if you prefer the player to keep iterating on their pattern. :)
Overall amazing work, keep it up!
