# Open Geometry Wars for AmigaOS 4.1 FE

Open Geometry Wars aims to be an extremely faithful recreation of 
Geometry Wars Retro Evolved.

## Installation

Extract the archive wherever you want and run the *opengw* binary.

## How to play

Pressing the keys 1 to 4 selecting the ship and colour. Multiplayer is 
something that is not working quite well. It is a limitation of the original
game, and not the port. So I propose playing a one player games for now.

So, pressing the key 1 a couple of times, the game starts with the white ship.

- w,a,s,d: moving the ship
- cursor keys: shooting direction
- F1: Enable/Disable VSync
- F2: Enable/Disable glow effect
- F3: Enable/Disable grid smoothing
- F4: Enable/Disable particle smoothing
- F5: Enable/Disable enemy smoothing
- F6: Enable/Disable player smoothing
- F7: Enable/Disable star smoothing
- F8: Enable/Disable the grid
- F10: Fullscreen/Window switch

If the game is slow on your machine, try to disable the grid (F8) and 
the VSync (F1)
