In the ingenious puzzle-platform game Bombastic, a little trigger can set off an explosion. That's because you are the bomb. Exploding is kind of your mission.

But unlike ordinary bombs, you can survive the explosion. If you come in contact with an orange block (that's the block with the big exclamation mark), that block will explode along with its neighbors. If you detonate it near a cannon, the cannon will fire. Tactical explosions combined with wall jumps, portals, and other bits make for a satisfying puzzle game in which all blocks on each level must be destroyed.

Though billed as a demo, there are more stages than most free puzzle games, and Bombastic is an elegant puzzle game with a neat, minimalist aesthetic that I'm curious to see how it expands.
