This is such a lovely game! I ran it via Bluestacks so was playing via the mouse rather than touch, but having had a quick go I will definitely install it to my mobile later.
One of the things I really like about your game is the message that it sends, recycle, clear up our oceans. The Boss was fab too, loved the bottles sticking out of his/her head. Nice idea with the rubbish gradually moving towards the beach. I also like that you have consistency, for example, the harder to break “blocks” are the barrels, which fits with the theme of the game, the two hit “blocks” appear to be the cans, and the sprite updates to reflect it’s been hit.
You have included a load of functionality in your game that I’ve not even looked at yet, although I did spot the high scores (sadly I didn’t quite do well enough) and customisation, unlocks etc.
Really fun audio, graphics a really enjoyable game. Well done for not only completing your game but also launching it via the app store, and of course to your brother for his art!
