Splice (PC)
This is a puzzle game with a very unique UI (user interface), since the menus are rather unconventional, like one of those futuristic ones where the menus are floating. Once you understand how to navigate the menus, then it's no problem.
In each puzzle, the DNA structure must match the lined structure, and to do that, parts of the DNA must be dragged to match the structure. It's like a tree, where you have to adjust the branches to form the intended "tree" that the puzzle wants you to make. Looking at the game might make you think this game's complicated, but it's in fact quite simple to play.
Certain puzzles allow the player to complete below the number of allowed moves, in which case the player gets an "Angelic" ranking, which means they managed to be efficient. Interestingly, while not every puzzle are generous in the move count, there is an achievement for getting every puzzle where it's possible to do so. I haven't beaten this game 100% yet, but in due time I will have done it.
Besides the creative UI, this game has wonderful piano tunes. Here's one sample:
