"""Dying Phone — a single-screen 2D platformer of ridiculous traps.

Story: your phone is dying. Reach the charger at the end of each level before
the battery runs out. The level is littered with obvious and (mostly) hidden
traps. Touch one and you're instantly respawned at the start — traps reset.

Controls:
    A / D (or arrows)  move
    Space / W / Up     jump (hold for higher, tap for a hop)
    S + Space          drop through one-way platforms
    R                  give up and respawn
    Esc                quit

Usage:
    python main.py                # play every level in ./levels
    python main.py levels/foo.yaml [more.yaml ...]   # play specific levels
    python main.py --debug        # force debug view on for all levels
