Love the concept of the game (also)! I liked timing the bomb with moving/falling tile sets. I wasn't very good at it, but I found the controls very intuitive. Using the mouse and numbers to select available patterns was a good way to accomplish the mechanics needed. I only played a few minutes. Perhaps an explorer/cheat mode that gives access to all possible shapes would be a fun way to click and boom everything - (maybe like a tutorial or practice level would give you access to such an entire list of shapes just to see how things go)
