Gameplay:

1. Navigate through a massive sidescrolling forest world with the camera following you
2. Jump through platforms from below - all platforms are one-way!
3. Explore 9 distinct sections across the 6400px world:
   • Section 1: Tutorial area with easy jumps (0-800px)
   • Section 2: Stepping stones over pits (800-1500px)
   • Section 3: Mid-level maze with multiple paths (1500-2200px)
   • Section 4: Tall tower climb requiring precise jumping (2200-2800px)
   • Section 5: Long jump challenge testing your timing (2800-3500px)
   • Section 6: High peaks with vertical exploration (3500-4200px)
   • Section 7: Cave-like platforming section (4200-4900px)
   • Section 8: Multi-layer platforming puzzles (4900-5600px)
   • Section 9: Final descent to the end (5600-6400px)
4. Meet 27 NPCs scattered throughout the forest to earn points
5. Use momentum and timing to reach difficult platforms
6. Enjoy the parallax forest background with trees, bushes, and flowers
7. Watch the NPCs as they autonomously explore and jump around!

Character Sprites

The game includes various character sprites:

• Player character
• NPCs (npc1, npc2)
• Special characters: Ding Gusen, Gress Gusen, Lanterne Gusen, Luna Gusen, Spaghetti Gusen, Wireless Gusen, Generator Gusen
• Additional sprites (sprite1-5)

All sprites use a 2-frame directional animation system where the image is split horizontally:

• Top half = Left movement animation
• Bottom half = Right movement animation

The game automatically switches between frames based on the character's horizontal movement direction.
