O-Line Particle Accelerator is a physics-driven, arcade-style roguelike where you build an offensive line of bouncing, colliding linemen and drive down the field for a touchdown. BUILD YOUR TEAM Build a team of lineman, and drive down the field. Score a touchdown and you win the game! Turn it over and you lose. After each down, use Fantasy Points to upgrade your team, applying unique Boosts and Stickers to give your roster powerful abilities on the field. GREAT OFFLINE PLAY EXPERIENCE This game is free, totally offline, has no ads and collects no data. Perfect game to play on a quick commute on the train, and perfect to sink your teeth into for a multi-hour flight. Also great to play at home if that's your thing! MUSIC, SOUND AND HAPTICS Trancelike adaptive music which changes depending on the phase of the game! ADAPTIVE SOUND: If you'd prefer to listen to your own tunes (or watch Funny Moment Video Compilations while you play), this game dynamically disables and re-enables its music and SFX when background audio/video is playing. SATISFYING HAPTIC FEEDBACK: No sound? No problem! Enjoy the satisfying haptic feedback when your players collide on the field and when the yards are tallied up after each down. CONTENT Plenty of content! 5 UNIQUE STARTING TEAMS: Each team has totally unique strategies and weaknesses. Run with standard rosters, Play as a Whale Family, or manage an Alien Monster that absorbs a teammate every round! 9 DIFFICULTY LEVELS: Each stake dramatically changes the difficulty of the game. Enemy stickers, random injuries, starting from the 0 yard line, and more. ENDLESS MODE: After a touchdown, continue the game with your team as enemies continue to grow stronger exponentially!
