This is a game that I made a while ago. It is not very good. This image sums it up quite well (in my opinion).

Here are some screenshots of the game. They look nothing like the above image, for obvious reasons.

There's a help section integrated right into the game, but most Game Maker users would ignore that and ask me what the controls are. Therefore, I will state them here. WASD moves, but you can set it to the arrow keys if you really insist/have no experience with PC games. The mouse and left mouse button aim and shoot. The right mouse button reverses the flow of time from forwards to backwards and vice versa. The spacebar freezes time. The clock in the middle lets you know how much longer you can reload.

Here is the download. Is is provided in .zip format because all .exes are virii and .rars are for terrorists.
