Nice splash screen ;-P
It's great fun to play and has a lot of potential for expansion...
Here are my constructive criticisms:
- Remember the state / position of buttons and menus between simulations;
- Consider more intuitive default locations for some of the UI elements (avoid overlap);
- Center the workspace when the screen size changes (ie, the grid should be in the middle of the screen by default);
Some bugs I discovered;
- Sometimes the polygons slip through small gaps when mass is high;
- Occasionally the polygons just disappear all together;
- When using the COPY polygon feature I can place the polygon outside the intended workspace area;
Otherwise it's a great effort!
