Hello, Badspot.
I find Blockland control scheme a bit sturdy and non-intuitive at times when using it with mouse, namely block placing.
So, while leaving numpad control, as this is what most players are accustomed with, I'd like to propose some new ghost brick movement control as alternative.
CTRL-mousewheel - moving on X axis (think num4(wheeldown)/num6(wheelup)).
Shift+mousewheel - moving on Z axis (think num2/num8).
Alt+mousewheel - moving on Y axis (think num1/num3).
Ctrl+Shift+mousewheel - rotating brick left/right (think num7/num9).
If supershift is turned on, alt+mousewheel will behave like num5/numplus.
What do you think about it? It would make those control more fun and engaging, because you won't need to travel your hand from mouse to numpad to build stuff, you just rest your left hand on WSAD (or mouse if you're lefty) and right on mouse (or arrows if you're lefty). Actual brick placing can be bind to mouse (my personal fav is ctrl+LMB), so it will be more fun.
So how about it?
Also, good luck with your platformer thingy. Will buy it for sure. I hope it'll have modding as advanced as one in Blockland when the time comes.
