Hey hey, time for a small update! 
What happened during last 2 months:
- I’ve tested everything I wanted with UA experiments, unfortunately the best CPI was about ~$0.5 (with Playable Ads made on Defold) which is still too high for such type of game to be covered by monetisation
- Tested game with two hypercasual publishers - HomaGames and Voodoo, their tests showed even worse results - CPI higher than $1
- I also tested “Paid hypercasual” approach - the idea was to try to acquire installs to paid version of the game and see 1) if CPI can be lower than game price 2) if there is any organic traffic from paid games top charts;
Results for our exact game: 1) CPI was around $15 for game priced $0.99 2) there were about 0 organic installs/purchases from highest reached ranks as #top40 Puzzle & Arcade, #top300 Games, #top700 Overall in USA (more details in Russian here) - The game was published in Russian web-games catalogue Yandex.Games, direct link to the game is here. This catalogue works in alpha-mode now and the game generated about $15 in first month after release. Meh.
- I lost my job (our office was accidentally closed by the mother-company)
What’s next:
- Add more content: different materials for bricks - glass, concrete etc; different shapes of bricks - triangles, circles, boxes; modifiers and obstacles on levels; new characters, new backgrounds, new sounds;
- Try to make gameplay more dynamic, there are few ideas to check, maybe I’ll post test build here for the feedback, if anyone wants (for example, the ability to swoop down by tap on special button - should help to aim better and break final bricks)
- Make game paid and ask featuring from Apple on AppStore;
- Add ads and publish as F2P on GooglePlay;
Keep tuned
