Landmine Cube

In this puzzle game, you assume the role of a rolling cube assigned with the mission of gathering all the gems in each stage while steering clear of perilous landmines scattered across the ground. If you tread on a mine, you will forfeit a life, and if you deplete your lives, you will be required to restart the stage from the beginning. Fortunately, the cube is equipped with an alert system that notifies you when a landmine is close by, shining brightly to warn you of possible threat. With 21 stages to overcome, can you adeptly traverse the hazardous landscape and gather all the gems?
