I've completed Two Dots Level 260 yesterday! Woo hoo! I've also started posting videos of my gameplay on Youtube
My recap on the levels is as follows:
Level 243: Tough but not as bad as 242. Key is to get rid of the purple Monster as well as using squares to get your blue, green and yellow dots
Level 244: Get rid of some of the blue Monsters so that you can get some yellow dots. I realise the best is to have a long line of blue dots and then end with a square while being connected to the blue Monster. That is the most effective as you simultaneously get rid of all the blue dots as well as reduce the number of dots required to kill this particular blue Monster
Level 245/248/251/253/254/255: I didn't intentionally get rid of the Monsters but it irritated me by eating up my anchors thus its best to get rid of them if you can
Level 246: I got rid of the blue Monsters once I got blue sufficient dots.. for the rest of the Monsters it can be bad if it eats up your anchors!
Level 247/249/250/259: Aim is to clear the blocks using squares and then eventually you have to kill the Monsters although they can be useful in helping you create the squares...
Level 252/257: I got rid of the Monsters once I got sufficient dots!
Level 256: This was tough as the fire dots came back and there was a blue Monster. I used the blue Monster to kill some of the fire dots and concentrated on making squares to get rid of the blocks.
Level 258: If you use a crate and end up with the teardrop which is supposed to make all the dots the same colour, you will end up wasting one crate as no dots will change its colour as its still behind the blocks. Again, kill the Monsters although at the start they can be quite helpful in you being able to make squares!
Level 260: Similar to 256 except that they gave you a green and light blue Monster with fire dots, blocks and ice and you are supposed to fulfil yellow and dark blue dots plus crack the ice. This was a tough stage as well and I tried to clear one side first and then again many squares with the help of the Monsters and then kill them so that you can get your yellow and blue dots.
