Alan is a friend of mine, so obviously I'm biased. But I really love his games. As objectively as I can, I think they feature a lot of character and puzzles that will melt your mind, along with some amazing secret stuff that's even harder. This one's wonderful, and a step up in size, graphics, and sound from A Good Snowman is Hard to Build, with the same great attention to how the brain figures out puzzles and deep exploration of what's possible given a set of puzzle rules.
A ridiculously fun and horribly addictive game. The fact the aliens look like penguins only enhances the game. Simple to pick up but with a huge amount of playability and variety.
Wonderful game, clever concept. I would give it another star, maybe two, except it keeps crashing. I have a Samsung Galaxy Tab 3 on Android 4.4.2.
Great game, tough. Nice touches like cloud save, unlock all levels, etc. I really enjoy it, $5 is too much though.
Great little game. A little expensive.
Adorable, challenging, HEAPS of puzzles. Really really well made game and certainly worth your time and dollars!
