About this game

Block Stack is a stacking game with a unique twist,

not only do you have to stack blocks in a tower, but you now have to set the strength of each block you place. You will need to use timing to hold and release and the exact time a bar fills up in order to place the block.

If you hold for too long the block will break, and you will have to place it again.
If you don't hold for long enough the block will be in a weakened state, and there's a chance it will break when another block is added on top of it.
You can also utilize power-ups to help you.
Repair - increases a blocks strength
Auto Perfect - Automatically sets the strength of the current block to 100%
Rewind - Undo the last action
Stack Blocks in a tower but don't let it fall over!
