Use the arrow keys and the w,a,s,d keys to move, space and 0 to shoot. This is the first version, be kind.
The start up sometimes dose not work. there are two options: 1. Download it to the offline editor, it works fine there. 2. press "o" to override. Also, sometimes the green tank dose not take damage in the online version. If you are green just ignore it, looking for solution though.
