Great aesthetic, overall promising with a few holdups in execution.
The intro is simple and to the point, but could stand to move a little quicker, especially considering that players have most likely already read this blurb before opening the game. Rather than simply repeating the premise as we wait for the crash that's already happened, this opening would be a great opportunity to visually present the locations of the repair kits and what the enemies look like.
The movement was frustratingly sluggish, especially for a game set on the moon. This is compounded by the enemies, who are too fast to leave any room for error– It feels good to get quick-draw kills right as an enemy gets up in your face, not so much when you're being inescapably spammed by an enemy you can't outpace. The orange enemies are especially broken, to the point where fighting them becomes a question of how quickly you can kill them rather than actually being able to avoid their attack. Their beam definitely needs a limit on angular speed and / or a limit on how long and frequently they can fire.
The graphics and sound are nice though, and again, I see a lot of potential here. I'd love to see an expansion on this!
