TwoDots Level 119 Strategy and Tips

Restart the level until you can quickly make a square in the open area in the middle.
Focus on the the open area in the middle for making 2×2 squares instead of trying to lap the gaps with a square.
Any enclosed area counts counts as a square, so you can wrap around any gap and clear a square and get bombs from the dots inside.
Clear ice individually once you get down to 4-5 ice blocks remaining. Hopefully, you’ll have 15-20 moves left.
