TODO

• Feedback
  • Automaticly cycle through the cards in hand instead of giving the player control over it.
  • Swap piece colors (less racist...)
  • Short dash ability?
  • Make hand combos matter? (Like Black Jack, Poker, etc)
  • Enemy variance (comes in swarms, moves slower/harder hits)
  • More generally fun mechanics
  • Alternate ways of healing?
  • Some mechanic to add together cards of the same suit?
  • Joker should be the strongest card
• Balancing
  • 3 card hand vs 2 card hand
  • Suit buffs (clubs/hearts op)
  • Super enemies fire rate gets too high
  • Enemies start too slow then get too fast?
• Tweak
  • XP and score system
  • Scaling system and numbers
  • Super enemy numbers and mechanics
• Improve aim feel (mouse, arrow keys, joystick)
  • Issue: mouse is relative to player position (really camera posistion) not world position
    • Like locked camera in League
• Loading time/screen on web
  • Either calculate the loading time for the sound file or ?
• Purpose?
  • Trying to get somewhere?
  • Trying to protect/rescue something?
  • Spawn extra score pickups around the area
  • Should make you move around dynamically
    • Instead of a straight line
