Tanglewood

The puzzles were only mildly taxing, and each stage has a fresh game mechanic to introduce variety to the gameplay (but without overloading the player).

The puzzles are nice, the graphics (especially in later stages) are gorgeous, the music is fantastic, it supports a FOSS platform (Linux), a cute story which (if you are in to such thing) can get you hooked quite quick.

The minimal soundtrack is beautiful and the visuals are bright and colourful.

The game also uses its own unique sound effects package, so every sound was created especially for this game; unlike many other platformers on Steam.

The game's design is excellent – the difficulty and learning curve are perfectly managed so that puzzles and situations are challenging without ever feeling unfair, allowing the player to garner what they need to know from playing the game rather than anything ever being hinted to them, be it a tricksome puzzle or an intimidating enemy.

Nice looking and thematically distinct levels, the main character is cute and is decently animated, though I feel like maybe there could have been a few more animations, like an idle or such.
