Random Picross Nanogram

I was tired of playing bad picross games. So I've made my version!

Features

• Randomly generated pictures with endless content
• Juicy and comfortable controls
• Dark themed so you don't hurt your eyes
• Mistake mode: offers a more challenging mode where you can't make more mistake
• Local high score system (Time based)
• Very satisfying animation when you finish the pictogram (similar google's minesweeper)
• Really nice clicky audio feedback with an option to mute
• Auto-cross mode
• Customizable grid width and height
