v0.44

Hi all, sharing new updates of the game. Give it a try and share the feedback :)

• Galaxy Echo is now available as open test on Google Play (https://play.google.com/store/apps/details?id=com.bnogames.galaxyecho); pre-release version is being prepared.,
• Added a Rewind button, so the rewind can be now triggered manually instead of on death. This might be useful as Rewind grants dmg boost on higher levels - this will have to be mentioned somewhere, I'm evaluating how this can be presented.,
• Boss levels: bosses are now always appearing on predefined levels, with a custom intro & outro music. There are 6 bosses, 2 for each faction. Currently bosses are similar in their behavior, while I'm working on the customized boss mechanics now.,
• Updated skills: Lighting is now more powerful, especially on max level (5), as it was lagging behind Laser.,
• New skill: Rockets. Rockets have the homing projectiles exploding on contact with enemies.,
• Bunch of other game balances, improvements, refactoring
