Most instructions in-game. However, more can be found here: There's usually an island with something that can block cannonballs. You gotta go over the island to get the enemy ship. The 4 (soon 5) cannonballs are: Press the 1 key to get the normal stone ball. 9 POW, 1 WEIGHT. Press the 2 key to get the hot iron ball. 15 POW, 1.2 WEIGHT. Press the 3 key to get the cracked stone ball. 7 POW, 0.8 WEIGHT. Press the 4 key to get the chain shot. 5 POW, 1 WEIGHT. Enemy ship takes 20% more damage for 3 shots. SOON: Press the 5 key to get the grape shot. 4 POW, 0.5 WEIGHT. But you get 5 shots that follow a similar trajectory.
