1. Bombs. Activate a bomb to repel all adjacent objects 1 square away. Some solutions involve activating 1 bomb next to another.
3. Temporary arrows. Some squares have fixed directional arrows. Meaning, if your red square is moving to the left and it passes over an up arrow, then the red will go up of course. The Temporary arrows disappear after the first square lands on it.
4. The graphics are just about perfect.
5. Challenging, but not impossible levels to solve.
There are 100 levels and at the moment, I've solved about half.
