Such a zen game, loved the music. An undo button(even with the mouse) would be nice.

HOLY SHIT THIS GAME IS LOUD.

Can I give you some tips? You should do some parallax. And shooting should be by holding the left mouse button instead of pressing it. And it would be cool to have a map or something like that pointing where are the planets to land on. (Because it's kinda random when I find them. If you think it is important to not know where are they, maybe you could put some sort of radar noise that gets faster when you are next to planets).

The weapon selection is cool. But the combat mechanic is a little repetitive in a sense that you just forwardstrafe and backstrafe.

It starts to be cooler when you get ranged weapons and the fact that you get a lot of selection of weapons is a nice thing. I didn't got far enough, but it would be cool to have some vertically since you can jump.
