This game raises a few questions for me.
Firstly, why don't ALL games have grappling hooks? Secondly, why is "grappling hooks in space" such an underused genre??
Seriously fun mechanics here. grappling hooks are always a solid win in my book, but putting them in space really just elevated the grappling hook game for me. Using them to reel myself into enemies and smash them with my face is possibly the best use of a grappling hook science has discovered so far.
I can genuinely see this game play premise having some legs, if you wanted to pursue it. Spend a little time polishing the movement (like letting you release mid-grapple to change momentum without zipping straight into objects) and add some interesting level geometry (space derbies? Asteroid field?) and this game could be seriously swell.
Sidenote- loved the attention to detail of having gravity inside the ship. It's a small thing, but starting out with standard WASD controls it makes stepping out into space feel really exciting and new. Its clear a lot of thought was put into capturing that feeling.
