Love that idea! I'll look into it ^^
When you die in any level, you end up in the first level? That's definitely a bug. This game needs to start behaving itself!
I keep forgetting that people don't just know the controls by default lol. I'm calling it developer tunnel vision. I'll put some tutorials in the next update ^^
As for rotating the laser cube. You always hold it in the direction you pick it up. So I find the best way to use it is stand behind it so the laser firing end is facing away. Then pick it up.
