I really like the visuals for this, and the music is quite good as well. Something about the gravity and trajectory of the bombs did make it a little difficult to get the bombs to go where I wanted, but it was an passable challenge. I did really enjoy gaining some semblance of mastery, and trying to hold the bombs for just the right time makes for interesting decisions. I also think the procedural generation does a good job at varying up the experience run to run.
I think my main complaint would be with the bomb's blast. It expands and goes away slow enough that it gives you some leniency in timing your throws, but at the same time, it lingers long enough that even 2-3 seconds after the bomb explodes, you will still lose when running through that area. Also, if there are blocks above you and you prepare a bomb, the bomb shows up under the blocks. Several times I couldn't tell when/if I prepared my bomb, and couldn't time a throw properly, usually resulting in a game over.
Overall good, fun entry! I think just a couple of tweaks can make this even better. I've done several runs and imagine I may open this up later to try to get further in (I was only really able to get to about stage 4)
