This game's presentation is incredible! Seriously, the art and sound design are both top notch. I love the fact that the controls have you physically pressing buttons on your space ship and are written on sticky notes like the pilot kept forgetting and eventually wrote them down. In tandem with the music and damage sounds which trigger an alarm like your hull was just breached, this makes for a very immersive experience. This plays similarly to "Iron Lung", a pretty successful indie game so there's definitely a potential full game here.
I do feel like this game has a couple of rough edges that could be smoothed. First off, I actually quite like the radar pings every 10 seconds. It builds a bit of tension and I was often surprised where I had ended up after navigating blind for the duration. With that being said, it felt bad to take damage from something I was entirely unable to see or respond to. One idea might be to have a proximity sensor on board the ship that gave you some warning chirps if you came very close to an asteroid and were about to take damage. This means you'd still have to remember your surroundings from the radar ping earlier to know which direction you need to travel to avoid the asteroid, but it would give you some countermeasures to help preserve your health. Also, as mentioned by some previous commenters, a motivating system would be nice to prevent you from only moving when the radar ping is active (maybe oxygen meter, deadly space radiation, moving asteroids or aliens that might damage you if you sit still, etc).
This is a sweet start to a game with a great visual and audio style. You guys nailed the atmosphere and I think only a couple of small changes to the gameplay would make this something truly special.
