Didn't see there was a topic for the GBA Jam, original post here: https://forum.gbadev.net/topic/58-dare-to-doku-our-gba-jam-2026-entry

Copy from that post:

Hi there!

We wanted to create a 'star battle' puzzle game (also known as 'queens') for the Game Boy Advance. Since we are also working on our main GBA game Dare To Square at the moment we set in in the same setting, using the characters/players from that game. Hence the name Dare To Doku!

The goal of the game is to find all players hidden in the grid. You will need to apply a basic set of rules to deduct the locations, similar to minesweeper.

The game features 10.000 unique levels (with a grid size of 4 through 10), a challenge mode with leaderboard and a small tutorial to explain the rules of the game.

The game was developed for the GBA Jam 2026 and can be played here: https://daretosquare.itch.io/dare-to-doku

If you like this game, maybe you'd also be interested in our main game Dare To Square (which will be getting a physical release soon). A demo can be played here: https://daretosquare.itch.io/dare-to-square-demo

Below are some screenshots of the game:
