The announced update has arrived. The improvements of version 1.1 are the following:

A new main menu has been designed
In the selection of stages it is better to distinguish between the levels as such and the store or "hangar".
A configuration option was added with the possibility of modifying the volume of the music and the effects separately.
A third option to display the game information and credits.

In the gameplay itself, the control axis was modified, which received much criticism as it was mistaken for a crosshair.
The sound of hitting and destroying an enemy now has plain volume, regardless of distance, it has no attenuation.
This is to know more easily when the target has been hit.

These improvements mainly affect the gameplay of what is already there, but later I want to upload new levels and enemies.
