I played one of the Learn 2 Fly games a few years back I'm not really sure which one it was but I remember sitting down and wasting a night on it. So when I saw this pop up on steam I had to try it and I have to say I was not disappointed with the time I spent on it over the past few days.

Pros:
-Free to play, In the true sense yes there are in app purchases but everything in the game can be unlocked for free with very little grinding compared to other games.
-Nice simple introduction video lays out why you are playing as a penguin trying to get to space.
-Relaxing music, while very repetitive you never notice.
-Dubstep Drive, Possibly the greatest thing in the game The Dubstep Drive, I just wish it played more than one song.
-Character customization, though I personally didn't make any use of this.
-Achievements
-Clearly listed goals giving you something to work towards
-Multiple game modes laying out different types of challenges
-I almost forgot memes and pop culture references everywhere.
-My last but probably most important pro is something that usually doesn't have much of an impact in my reviews but the community for this game, the guides they write, the posts on the forums, Even the Dev himself posting regularly and everyone is very friendly and helpful which with this type of single player game you wouldn't think would make much of a difference but it does when you are trying to figure out what all of the unlocks and parts do and the most effective way to use them together.

Cons:
-This is where they should be but I honestly can't think of any. Well done developers.

I will admit this game isn't for everyone not everyone likes casual games or this type of strategy game but I highly recommend it. Even if you are just looking for something to waste 30 minutes on give it a try you might like it. This isn't the place for it but I would like to thank the Developer of this game for taking the chance and bringing it to Steam without that I would have never even known it existed.
