Test Stuff

This is `get-a-key-go-to-exit-keep-alive`. Completely in 2D. There are no any story; you playing as the red square, looking for keys around on a level. Your enemies are:

Idiot: blue square with rotating arrows, can move only up or down.
The Drunken Bot: looks like player, but it`s green and it smiles to you. Walks in random direction, the same way like player.
A turret: shots in random direction with a constant interval. Bullets can fly through the walls.
The Boss: randomly moves left or right at the top of level, fires from two guns. Starts raging, when his health becomes low.
There are no savegames between levels, so if you`ll lost all backups and die somewhere at 15th level (for example), you will be returned to the first level. At the game's begin you have five backups; collecting of a big green square will give you one more backup (aka 1-UP).
