Summary: I really wanted to like this game as I usually like puzzle platformer games. As others have mentioned the graphics and music are great. Controls are not so great, even with a gamepad. The main reason I didn't like the game is that collecting things (whatever they are) makes up a large part of the game. The platforming and puzzles elements are nothing special and I really dislike games based on collecting things. If that is your type of game you will probably like Fly'n.
Summary: I'm surprised this games hasn't got more attention. It's a platformer that departs sufficiently from the normal run and jump format that it feels fresh. It has auto-scroller-ish sections, boss battles as well as puzzle and exploration focused levels. You'd think that would mean the game lacks focus or polish but that isn't the case in this instance. Instead it provides a nice chance of pace through the game to ensure you don't get bored.
Summary: The visuals are absolutely beautiful, with its smooth animations, vivid environments, and gorgeous detail. Cuteness aside, it can get really challenging, when not downright frustrating. It's not a game that will redefine the genre, but it's a great achievement indeed and, most importantly, it's a lot of fun.
Summary: Great game. It's a "point A to point B" platformer, but with significant gameplay innovations - four characters with different capabilities, two "layers" of world that the player can switch between. Some levels require speedruns, others allow for exploration. Great pacing, fluid controls, excellent music, leaderboards. Nicely tuned difficulty progression, good amount of content.
Summary: I have yet to finish this game, but so far it's blown me away. The graphics and gameplay remind me a little bit or Rayman Origins, except it's a little more involved, with more puzzles and gameplay elements. The music suits the game extremely well. Overall just a great game. One of those rare, refreshing works of art that offers something unique to PC gamers. Please buy this game and support the developers!
Summary: Solid 10, great game, id write more, but i think the other 3 10s here pretty much summed it up. If you like platformers,you wont be disapointed. This is the best platformer ive played in years! love it!
Summary: This game is so great it's almost unbelievable. Everything is at the top possible quality - graphics, sound, gameplay, everything is amazing. When you start playing it you will be instantly hypnotized. Visual style is a mix of LocoRoco, Patapon and Flow - detailed backgrounds, fluid animation, amazing particle effects, levels are a vivid mix of rainbow colors resembling dream landscapes.
Summary: I bought this game and played it in a single, 6 hour session. It was a difficult one to put down. Wonderful art style, music, game play, variety, pacing... it's a wonderful platformer. I played it with an Xbox controller and everything felt crisp and tight. This $10 provides MUCH more fun than many AAA titles I've purchased recently.
