Rules:
1. Write digits from 0 to 9 in each row and each column.
2. Digits in cages doesn't repeat.
3. You are playing the game Donkey Kong. You have just finished the Stage 1 (Link for Stage 1) and now you are ready for Stage 2. The goal is to reach the princess (the star). The end of your last move should stop at the princess.
4. Start: You start at the white triangle (r10c1) and move the number of spaces the digit on the triangle, and continue your journey. You have to move the number of space equal to the digit you stop on the grid.
5. Ladders: Ladders shown by grey arrows can be used to go up or down. Moving up or down a ladder is not free; it costs a movement like any other movement. Ladders act also as a thermometer if they are used. The bulb is then the location you enter the first time when you use the ladder and the tip is the end of the ladder (upward or downward). Afterwards, You can only use ladders in the direction of the thermometer created from the bulb to the tip.
6. Elevators: The elevator in column 3 can be used to go up only. The other elevator in column 6 is to go down only. Moving up or down an elevator also costs a movement like any other movement. The four platforms in each elevator are moving, so you can enter or exit in any platform available. Like ladders, elevators act also as thermometers in the part you use them. The bulb is in the cell you enter when you used the elevator for the first time and the tip is when you left the elevator for the first time.
7. Half height platforms: You can also go up or down by using half height platforms. If you go up that way, you must first go into the half height platform and then go up a square before going to the full height platform. You cannot move diagonally. It is similar if you want to go down. It is possible to move fast enough in elevators to use them as static half height platforms to go up or down. i.e. you can go from r6c7 to r5c5 (using a movement of 3 spaces) or from r5c5 to r5c7 even if the elevator is going down.
8. Parasol and purse (light bulbs): The princess dropped these important items in the grid and you must get both of them before reaching the princess. To get these items your movement must stop exactly in the cell they are located (r3c10 and r5c1).
9. Movement restriction: You can only change direction after you stop on the parasol or the purse. Every 3 consecutive moves you do, contains one digit from 1,2,3, one digit from 4,5,6 and one digit from 7,8,9. You must use all of the digit and only once each before reaching the princess. The digit on the princess do not follow these restrictions. The princess decides the digit she wants, following sudoku rule.
10. Fireballs: There are two fireballs shown by white lozenges. The white arrows close to them indicate their last movement direction and they continue their movement in the same direction unless they have no choice to go back. They can use ladders, but they cannot use half height platforms or elevators. i.e.: The fireball in r8c4 will do an infinite clockwise circle. The fireball in r5c10 will first reach r7c9 before going up to r3c10 and so on. They move a number of spaces depending on your movement. 1 space if you move 1,2,3 spaces, 2 spaces if you move 4,5,6 spaces and 3 spaces if you move 7,8,9 spaces. You always move first and then the fireballs move. You are not allowed to cross or jump over a fireball.
11. Jacks (circles): Donkey Kong is trying to stop you and he throws jacks (big springs) shown by circles. The full circle is the starting position and the dashed circles represent the trajectory of the Jacks. Jacks can move diagonally and move the same way as fireballs (depending of your move). Your movement cannot stop anywhere along that trajectory.
12. Fireballs and Jacks marking digits: Each time the fireballs or Jacks stopped their movement; they write in the cell they stopped the digit of your movement number since you started the Stage 2. Only the first Jacks throwed by Donkey Kong write digits. Fireballs move and write digits before Jacks do. If a digit was already written by the fireball in the cell during a previous move, nothing happens, otherwise any digit you entered by other means (you or jack) must correspond to what the fireball want to write. i.e.: if your first move is 5 spaces, then each Fireball and the Jack will move 2 spaces along their path and write the digit 1 in the cell they stopped. On your second move they will write the digit 2 and so on.
13. Bug corrected: The end path of Jacks r10c9 is really the end. They don’t come back at the top of the grid like in Stage 1.

Added a rule about ladders to prevent a possible second solution.
