I love the art and sound. And I think you're on to something with the gameplay. I kept playing, and I really wanted to progress further, but I felt the gameplay was very slow waiting for the bomb to land in the right spot so I could progress. Reading some other comments, it turns out that I can also move the bombs when they're about to explode, but I didn't discover that on my own through gameplay.
I also found it frustrating to die, one hit, when a bomb would fall on you. This felt too punishing, because they fall at random, and they fall very quickly, leaving very little room for skill. It felt more random than anything, and that wasn't fun.
Giving this feedback, because I'd love to see this taken further, game-tested and polished. Maybe more bomb types, and maybe a mechanic to speed up the progression. There is something very at the base of this game.
