Hi! I recently released my fist game on google's PlayStore and it's completely  free and without ads. Try it if you want and let me know how you feel about my work  and how can i improve it!

The game is a simple arcade game where you have to shoot enemies to make points, there is also a multiplayer offline mode that is based on the same idea of the single  player, but you have two ships that shoot at each other  while  trying  to avoid lasers shoots from the enemy player's ship and his army.
