Brilliant! .. Buuttt
A very cool and relaxing concept, I enjoyed the game very much and found no real flaws in it, no bugs. Its very straight forwards and quite amusing.
My Three Complaints,
Not enough extra points for NOT using Dynamite. I could clear every level, sept stage 19 with at least Half of my Dynamite left and the bonus points, whilst meaningless, still we're unsatisfying. Maybe have a harder setting that only gives half the Dynamite you have normally.
Not enough variety. I liked the concept of bring it down to a certain height, then also on a few, not to let it hit a building placed to the right. It would have been nice for some other difficulties, say, buildings either side of you, obsticles at certain heights, etc.
Not enough Levels. 20 Is a nice number, but I breeze through them to quickly!
Still, my complaints are no cause for a lower score, great game 10/10.
