Some players have been asking for a couple features:

• Ability to use mouse for fire/bomb (mouse position is not accounted for)
  
• When using autofire, pressing fire should override autofire
  

These have been addressed in this update.
Thank you for providing feedback and thank you for playing!

Due to Gamma Zero lacking online leaderboards, feel free to use the community pages to post videos and high scores.

Also I would like to thank The Hidden Fortress for the shoutout!
