Some Post-Jam fixes

This is almost the same code as what was entered in the Jam, but with a pair of fixes that make it cooler. Doesn't count as an entry in the Jam..

Gameplay

This is a clone of the BSD game Robots, with a simple time travel mechanic. You (@) are surrounded by robots (X). The robots are trying to crush you. Don't let them reach you!

The goal of the game is to destroy all the robots by causing them to crash against each other. You can move around, and you can jump back in time. You start with 10 time fuel. Jumping one unit of time back costs one unit of fuel. Every five second-ish you get some more time fuel.

The robots all move simultaneously, but you move asynchronously at a different rate.

Controls

• WASD to move;
• 1-9 to jump back 1-9 units of time.

Known Issues

• keypresses get buffered and lag;
• flickers like mad;
• no fuel gauge;
• Leaving the screen is allowed.

Requirements

.NET 4.5, but only nominally. I can downgrade the requirement to 3.5 without changing code.
