Hi folks! Your friendly forum mod Tee here with a handy thread to help anyone who is stuck somewhere in Samurai Pig! I've spent about three hours completing the first area and another few hours going back for all three stars, so I'd like to give you all an opportunity to post here if you're stuck!
Here's some general tips that might help you out:
Tapping - How you tap SP affects how he drops. If you're having trouble getting him to drop a certain way, try tapping faster or slower and see how it affects the outcome!
Gravity - Use gravity to your advantage! Sometimes you can place a block hanging off a ledge so that when you tap SP, the block will start to fall too! You can use this to get a block to land a certain way or crush an enemy. Be careful not to crush the kidnapped pigs, though!
Timing - Sometimes you have multiple SPs that you have to tap in the right order to get the best outcome in a stage. As with the tapping advice, you might have to try a couple of times before it works. Don't give up!
If anyone would like to post some of their tips, I'll add them to this list and credit the author! Also, please post any questions about a particular stage and we'll do our best to help you out!
