The beautiful, polished Atma feels like a 'full' game compressed to a fine jewel, an action adventure with no fat you can play for free over an afternoon or so.
The impressive pixel art reminds of Hyper Lift Drifter (though they could have maybe toned down the bloom slightly), while the central mechanic recalls the 'pause the game and draw lines on the screen' of the similarly Zelda-inspired Okami.
You're Shaya, a spiritual guardian, and you're attempting to aid your lover who has become trapped between the living and spirit realms. This you do by exploring a gorgeous world and using your powers to influence it, making the occasional moral choice along the way.
Your first power is simply to dispatch enemies, as you slow the action by hitting the space bar and draw connecting lines between the creatures, but pretty soon you gain the ability to manipulate the wind. As you may have guessed, you use directional wind gusts to blow blocks this way and that, and to activate wind-powered switches. Typical Zelda stuff, but implemented well.
