Regarding playability and sustainability, I added a "Power" system, which is the one in the lower right corner of the picture. Using power allows players to unlock skins and purchase items. Each coin insertion grants 1 power, and catching a doll awards an additional 5 power. The battery has corresponding power animations to try to give players a sense of satisfaction and achievement when obtaining power.

Using power, you can purchase props and unlock claw machine skins.

Wings can make the doll fly for a period of time.

The hammer can knock the doll out of the high platform.

The bomb can blast apart piles of dolls.
