One logic puzzle a day: the numbers tell how many pixels to paint per row and column. Solve it and a secret picture appears. In Portuguese.
ClaudeCare.exe — a Claude Code mascot pet (PT-BR)

O Estagiário — corporate idle game (PT-BR)
Close tickets, buy coffee, hire the intern's intern and climb to CTO. An idle game about Brazilian corporate life. In Portuguese.
