Instructions: Use the left and right arrow keys to control Dropple. Collect all of the coins in a level to advance. You have unlimited lives, and your progress is saved at each level - you can continue from where you left off in a previous game by selecting 'Resume Game' from the main menu.
Just a head's up: This game gets TOUGH quickly. It takes a little while to get used to controlling Dropple. Try using a light touch on the keys for better control.
