Flutter + Flame, no sprite sheets: every visual is rendered with Canvas painters and every sound is synthesized by a Python script. Forgiving mechanics with teeth — clip a hurdle and you trip instead of dying, but the inspector starts chasing and the second mistake is the last. Near-miss bonuses, magnets, shields, and 2x multipliers.
