You are Charlie the Charger. Jump over the obstacles and duck under the pillars to move forward. Every 100 points you level up and the game speeds up.
Controls
Computer:Space jump · hold S crouch
Phone: tap the right side to jump · hold the left side to crouch
Obstacles
Hurdles, wall & fire: jump over them.
Red pillars: you can't jump these. Crouch to slide under the bar.
Boss fight (Boss Mode, level 5)
The Rebel throws fireballs along the ground. Jump over them.
He also throws footballs at head height. Crouch to dodge them or parry them.
How to parry: Jump first, then press jump again when you see the gold ring around the football. This will then hit the football back at the Rebel, doing damage.
Dodging chips his health bar. Parries hit much harder. Empty the bar to win.
