If you like puzzles that make your head spin, then Melty is a great game for you!
Use your arrow keys to rotate the background. In this manner, you will move the ice blocks to the fire blocks in order to melt them. Melt the block with the star to complete the level.
There are lots of “twists” that you will learn as you play. For instance, you can click and drag to move the wooden blocks. That is why it is suggested you play the levels in order, even though you can skip all the way to 96 and start there if you want.
