Simple, fun, and mildly stress inducing at times, 'Naut is a good starting point for a bigger, better game. What starts as a fun field trip through space, slowly reveals to be a race against time as you're constantly running low on oxygen, having to balance your time between finding all the happy little aliens you want to be friends with and trying not to die alone in space from suffocation because you were just a few steps from that last O² tank. Your final thoughts turning to your friends and family as you wonder why you went to space on this journey by yourself. Oh, why?! Why?! Now they'll never know what became of you, meanwhile you'll be a skeleton lost on some empty planet. Oh, and the graphics and audio are pretty nice as well, with the soundtrack being pretty adventurous sounding and the visuals reminding me a bit of soft clay.While many things could be added to the game over time, one thing I would suggest is a timer for when you're about to run out of oxygen. Maybe the final ten seconds or so. The screen fading to black is a nice touch, but only works well as an indicator when it fades until you die.
Good job on this, dev. You made a fun thing.
