When I first played the game, I didn't know what to do. The how-to I read wasn't helping to me. Perhaps you could add a "tutorial" when someone first launches the game? I know the mechanics aren't hard but it was hard for me to get used to. I managed to get myself used to after couple attempts, though.

Gameplay wise, once I got used to it, it was actually challenging. I mean in a positive way. It was probably the most enjoyable game from this whole gamejam submission. I also like the detail where I could see the current fuel amount, velocity etc. It not only helped me to land properly, but also made me think as if I'm actually landing.

On the graphics wise, I would call it just about adequate. I understand that you are recreating the retro game and hence bringing the feel of the retro look, but perhaps a bit of a graphical touch would've been nicer.

Visibility of the lunar landing module could've been improved. The leg part which contained a width of 1 pixel, was barely noticeable especially the module being relatively small to the other elements.

A feature I wish I had would be manual zooming. Sometimes zooming gets up so close that I don't know where I'm supposed to land. Also because of the fact that zooming transition just happens instant, made me think "woah what happened". I first thought it was a glitch.

Lastly on the graphics side, more effects could've been added. A simple game without that much of a functionality nor good graphics, adding effects is the only way to spice your game up. Screen shake on crash is a good example. Even a simple effect can influence the game in a bigger way.

One little thing which bothered me was that the volume setting wasn't saving. I had to adjust the volume manually again every time I launched the game. It doesn't ruin the game completely, but it certainly would've been a bonus point if you implemented the settings saving feature.

P.S. I raged couple times.

Edit: Striked couple things through as you updated your game.
