Dino Dash

Operational Brief

Dino Dash is a 3-lane endless runner with a faux-perspective road that converges to the horizon. A cheerful blocky T-Rex auto-runs toward the screen while logs, hanging vines and golden apples rush up out of the distance, scaling in as they approach. Read the lane, pick the right move, and keep the run alive — pure one-screen arcade flow, no install.

Engineered in-house at Studio Eighty Five as a showcase of lightweight HTML5 craft: a custom depth-projection renderer, zero physics dependencies, procedurally generated sprites, and a steady 60 FPS on phones in a single browser tab.

• Three lanes on a converging trapezoid road with depth-scaled obstacles
• Jump logs, slide under vines, weave lanes to dodge
• Golden-apple coin streak with an escalating score multiplier
• Near-miss bonuses, distance milestones, and a speed ramp over time
• Power-ups: a one-hit shield and an apple-vacuuming magnet
• Local best-score chase — instant load, no account, no friction

• Swipe / arrows: ← → change lane, ↑ jump (clears logs), ↓ slide (under vines)
• Collision = an obstacle reaching the dino's lane and depth band without the right evade
• Score = distance travelled + apples × streak; difficulty ramps via speed and spawn density
• Spawn director keeps at least one lane open so runs are always survivable
