Very cool game! I loved the tile-based tower defence, although it sometimes felt a bit too random (I was unlucky enough not to receive a candy factory for 4 levels straight, haha). Very cute animations and visual style, I loved that the kids are running away when their HP goes to 0, this was a very cute detail. From the strategic standpoint, I really liked the idea that you have to feed your currency to the towers; this created an interesting dilemma and made the enemy wave phase very dynamic. However, it was somewhat unintuitive that tower charges are time based, I burned a lot of candies before I understood that this is the case. Maybe consider making tower charges shot-based, so that they only spend candy when they are shooting. Just an idea.
Thank you for the game!
