Try Not to Be Too Aggressive
One thing I will say about the Adventures of Pip is that there's no need to rush through each level. Take your time with it because it can be as much a puzzle game as it can a platformer. There's no time limit to worry about so definitely feel free to take it easy in tricky areas.
The reason why I say not to be too aggressive is that you'll be relying heavily on checkpoints. When you die, you start off at the most recent checkpoint. This is good of course because you don't need to worry about starting over from the beginning.
However, sometimes you'll find yourself taking a bit of a detour with no checkpoints nearby. And if you die without completing your hidden route and discovering what it has to offer, then you'll start back at the checkpoint, meaning you'll have go on a little trip to get back to where you were. But, if you got through the path and collected the rewards then great, you're all set to move forward.
Know When to Switch Your Size
This is something that may take a little time to get used to but, as mentioned, you will be able to almost freely change between 8-bit and a single pixel. In many areas, there will be these crystal-like creatures roaming around that, when you hit them, will turn Pip into an 8-bit character.
Just be careful not to run into them as they will take a heart away. Jump on top of them to crush them and transform yourself. The majority of the time when you see these creatures, it means that you may have to perform a little switcheroo.
So you might need to switch to a single pixel in mid-air for example. There will be obstacles such as blocks that will be in your way sometimes. Switching back to a single pixel will cause an explosion that will destroy the obstacles in your way. Being a single-pixel also allows you to jump higher on objects that make you bounce. But knowing when to properly switch can be key to success in grabbing treasures among other things. And don't worry, the crystal creatures respawn, so if you need to change back to a more humanoid appearance then you can do so.
Head to The Shop
Adventures of Pip is full of treasures if you're observant and curious enough. There are chests that are scattered around each level just waiting to be opened. Some are pretty easy to get while others require you to make some moves and go through secret areas (kind of like we talked about).
After you've filled Pip's pockets with gold, head to the shop and purchase that platinum chain you always wanted (just kidding). But no, the store is open for you to buy things that can help you out on your adventure through the various levels of the game.
You can visit the town where you started from to get to the store. You'll need to make sure you're not playing on a level so make sure to make a visit before advancing as you would need to quit the level in order to go to the city. And fortunately, our friend in the shop still is his 8-bit self so the evil queen did not turn him into a single-pixel (lucky fellow indeed).
