World 1: Tutorial World

Level 1-
Difficulty: 0/5
Do I really need to explain this? First, jump to the left platform using the up and left arrow keys. Next, jump to the middle platform (using the up and right arrow keys). After that, jump to the right platform, and you're at the goal (a dark pink circle). There are no obstacles in this level, so its impossible to lose a life.

Level 2-
Difficulty: 1/5
I wonder what the red does to you? SPOILER: It makes you lose a life. Whatever you do, ALWAYS avoid red. This level is really basic, and has 2 small red lines that you have to jump over. Just head to the right, jump over the two red lines, and you're at the goal.

Level 3-
Difficulty: 1/5
When, you fist see the level, you should see an unusual light blue/indigo line. What does it do? Well, it's a trampoline, and it bounces you high into the level. All you have to do in this level is go on the trampoline, head to the right above the vertical line of red, and you're at the goal.

Level 4-
Difficulty: 1/5
This level is underwater, so the game physics are a bit different. Before you beat the level, just make sure that you've mastered the underwater controls. In this level, head to the right, then, up, and then left. Near the end of the level, there are two easily avoidable red lines. After you pass those, you're at the end of the level.

Level 5-
Difficulty: 1/5
This level has water on the top and the bottom of the level, which in my opinion, is very awesome. You should notice that the layout of the level is nearly identical to level 1, except that there's water, and two red lines. First, jump to the left platform, and then to the middle one. It looks like you're supposed to jump to the right platform, but it's much easier to jump into the water right above you (you would have to touch the water if you were going to jump to the right platform anyway). After you're in the water at the top of the level, head left towards the goal. Horray, you beat World 1!

Level 7-
Difficulty:2/5
Level 7 introduces you to moving red dots. These guys can be a pain in the later levels, but they luckily move slow in this one. First, jump on the log platform, and head right. When the red dot is near you, simply jump over it, it should be pretty easy. Next, jump to the platform at the right of the level (there's red/lava below you, so be careful). Before you jump to the upper section of the level, pay attention to the red dot's movements. When it's heading left, jump left to the upper-right platform (there's 2 platforms on the upper half of the level). When the red dot is heading right across the gap, jump over the gap (and also, the red dot), and quickly head left. Then, jump over the red line, and jump to the goal.
