Hi, and thanks for the promo code (EAWXLW79FJYE)
I have had a quick play; I love physics games!
Just a couple of constructive comments if you don't mind...
1) A 'reset level' option would be helpful; I found myself having to destroy quite a few blocks even though I knew that I had already failed.
2) A 'destroy all remaining blocks' button would also be useful; sometimes I found that I had solved the level, but then had to spend time manually destroying quite a few remaining blocks just to complete the level.
3) Maybe it's just me, but it wasn't immediately apparent to me what I had to do (i.e. get the bomb onto the dark block); it took a few goes to realise what I had to achieve!
4) The game doesn't have much 'atmosphere'; I think some sound would be a great help and, perhaps, some other eye-candy rather than the initial 'bleak' blue background.
5) Some kind of scoring system would be great too; maybe a time limit based on a ticking countdown to get the adrenalin running.
I hope you will accept the above as constructive criticism; you have produced a playable game and got it into the App Store, which is more than I have achieved!
Thanks again for the promo code!
