It would be a shame for you to miss out on playing Merge Blast since it is a brand-new type of merging and shooting game all in one. This is a combination that isn't seen on the internet all that frequently, so you should definitely prepare yourself ready for something different and brand-new.
The tiles that are falling from the sky have numbers on them that indicate how many times you must strike them in order to collect their money, therefore you must use all of your skill to shoot them down in order to collect their money. Using the mouse, holding it while dragging, or your finger if you're on a phone or tablet, you can control the cannon.
If you lose all of your lives, represented by hearts, the game is finished, so be sure to shoot them down first to stop them from landing on top of your castle. As you gather more resources, you mix them to develop new abilities, launching them from the cannon with better accuracy to deal more damage to the enemy that are descending.
