Hidden Collectibles and Secrets.
If you want extra energy and a vaccine gun: Navigate straight to the end of the map without deviating from where you started. From here when you go right to the rainbow you can get diamonds each giving 10 energy and a vaccine gun (only in FPS mode) from the crate that can be used 50 times.
The game guides you through gold coins each giving 1 energy. Follow the road to the right behind where you started. Continue straight at the junction after the first bridge.
When you follow the road you will see the stars on the right at the top of the first hill you climb. If you look to the right from that location, you will see Yin Yang. There is the other vaccine gun (only in FPS mode) in the middle of this pond which you can use 50 times.
When you reach the center of the grass platforms in the air, you'll find the first key you need. This key opens the door to the big house behind the town.
At the town, the object in the market place on the right gives you 50 energy.
The second key found from the town house opens the door to the hut surrounded by walking flowers on the hill next to the grass platforms.
Inside the hut surrounded by walking flowers, there is the key to the first door of the castle on the hill that can also be climbed by platforms, ie the third key.
When you reach the center of the lava platforms in the air, you will find the fourth key you need. With this you can open the door of the mushroom house in the forest.
You can teleport from the mushroom house to the meteorite.
The fifth key in the meteorite is the key to the hut where you started the game. You can teleport back into the forest with the other teleport.
In the hut at the beginning, there is the sixth and the last key that opens the second door of the castle where the queen is held captive.
You can teleport from this monument next to the town to reach the castle on the hill by a shortcut which can also be climbed from the platforms.
