This is a 2D platformer challenge game.

Controls: WASD + J + Spacebar + E

Gamepad:
Left Joystick + RT + A + X

This is the first of Charlie's 100 challenges. In this game, you need to control an 8x14 pixel Charlie, using wall-jumping as the primary technique to climb a 16,200-pixel-high tower in a single attempt without saving.

I have personally verified every difficult section and ensured that it is possible to reach the top, so please rest assured. If you encounter any issues during the challenge, feel free to email me or post a screenshot in the comment section.

This game is extremely easy to pick up. Simply move left or right, jump with the spacebar, hold J in mid-air to wall-climb, and then press the opposite direction of the wall + jump to continue ascending. These are all the techniques in the game. The rest depends on your patience, confidence, and courage.
