I liked the game and managed to beat all the levels including secret level 7. In levels 5 and 6 I even found solutions that save 1 extra bomb. Snapping boxes to correct tiles is a good addition, otherwise it would be impossible to hit the right spot.
I really like the minimalist look and explosions look very cool in this environment.
My favorite moments were chaotic when boxes hit each other in chain reaction like billiards balls.
