I've got an executable going if you want to give my game a try. It's got only the mechanics done so far, but any feedback is appreciated!

I've got an itch.io page going, where you can download the game.

Keys are simple, aim and click to shoot, right mouse button to latch onto the walls and spacebar to jump (and use the jetpack).

Also, I tried to do some sort of wall jump, to add more velocity to the game, give some feedback on that.

I've been having a blast reading all these posts and going through the challenge of finishing a game jam on my own!
