Picked up again after ages
Remembered this from ages ago and picked it up again- fantastic and underrated little gem for puzzle lovers
This game is nicely designed and has smooth, nicely addictive gameplay! The levels are colourful and clever, and give you a great sense of achievement when completed. This is my favourite puzzle game on the AppStore I think! People moan about having to pay for more levels, but there are no ads, even before paying, and you have got to give them something in return for such a fantastic game. - trisnpod
Very good concept, lovely minimalist if design and a very clean set of colours that make a very enjoyable gameplay, however, with only 40 levels without unlocking more with in-app purchases it feels like a lite version of a full app. I would have preferred a lite app with those 20 levels and another app that unlocks all levels for no more than £2.
But, worth a play, even if you do complete all of the standard levels in under 2 hours.
