Basic Idea: Build blocks. Get keys!
Review: A game similar in spirit to Lode Runner, you must collect keys (instead of gold) on each level to get through the exit. And instead of digging holes, you can build and tear down blocks to misdirect enemies or create your own staircases to get to hard to reach places. The level designs can be tricky (perhaps too early even, before the player has a good grasp on things) but are generally satisfying to complete. The controls could be a little tighter, and I always hate time limits, but these are mild frustrations. Solid, but not great, puzzler.
