A downloadable game

(Read as "note-nogram") Made with Butano for GBA Jam 2022, partially inspired by Battle Picross by Sean Reid.


  • 21 original 12x12 picross puzzles to solve
  • cringy Japanese anime girl voice clips provided by me
  • story mode with three different endings decided by your picross solving skills
  • creator mode that allows making puzzles and sharing them via GBA save files[1]
  • tutorial mode that explains picross basics and a couple of strategy tips
  • original character cameos of some sort?


  • A button - color the square the pen cursor is pointing at/confirm option
  • B button - cross out the square/exit menu
  • D-pad - move the cursor (hint: pressing and holding a directional key while holding A or B on the picross grid will mark otherwise empty squares as either colored or crossed out in the selected direction)
  • Select - exit puzzle screen
  • Start (in creator mode) - save current puzzle[2]
  • L or R button (in creator mode) - toggle custom puzzle slots in save memory to write to (currently only three slots available, writing to occupied slots will overwrite them without notifying)

Hi there, I just finished a game jam where I made a nonagram game for the GBA too. I came here to see how you did a 12x12 grid as I ran out of sprite space in my game and was limited to an 8x8 grid.

As a picross addict, this is a really great game. I love the themeing and the music. Well done!


Þe font was really hard to read, but oþerwise it's a good game.


thanks for the feedback and kudos to you for using thorn!


This was a lot of fun. Ran it on an Analogue Pocket and did not run into any issues. The font was initially a little hard to read but you adjust pretty quickly. The graphics were nice and it felt very nostalgic for some reason. I am no good at these types of puzzles but doing them was enjoyable and straightforward. It'll be staying on my pocket for sure. I could use a hint feature but that's on me for not being good at these. Thanks for making this!


This was the game I was least excited for in the Jam (just because picross is such a known factor) and it was probably the second most fun, and the aesthetic is great, I really liked this.
