1 month passed from the last update. There some changes were made in the game:
- Game link is the same: Bouncy Catapult King 1.3.10
- Sounds and music added
- Some visual effects added, along with the trail; made it via ParticleFX as @Pkeod suggested, but today this awesome extension was released by @aglitchman , going to give it a try
- levels were rearranged and polished regarding players feedback and analytics
- some UI changes
Also the game is released in few countries on iOS currently - you can play it before I’ve ruined it with tons of ads

Yes, the changes might look minor as for 1 month of work, but it was a month of Facebook ads experiments, checking different creatives and approaches, learning how to make these creatives, understanding the rules of this game and burning some money, of course 
Currently we’re working on other color themes to see if brighter ones will work better, you can check the mock-ups:
