Controls:

• Arrow keys to move
• Space to jump
• Hold Z to charge/Release Z to attack
• Double-tap left or right to dash (ground only)

Mechanics:

• Hold Z to charge up attack. The longer you hold, the stronger the attack level will be.
• Level 0 attack does 0 damage.
• Level 1 attack does 1 damage.
• Level 2 attack does 2 damage.
• Level 3 attack does 2 damage and knocks back.
• Holding for charge too long will force a level 2 attack.
• Charging in air locks you into a slow fall.
• Charging is dash cancellable on ground only.
• No double jumping.
• While in the air, double tap down to fast fall.
• You can only attack once in the air.
• You can jump cancel attack recovery for level 2 and 3 attacks on hit. Meaning, you can jump and attack immediately after a successful attack in the air.
• Dash Shield prevents damage for one time use on the whole dash duration. Dash Shield becomes active again after scoring 20,000 more points from the moment the Dash Shield breaks.
• Dash recovery is jump cancellable.
• Holding left or right while jump cancelling the dash recovery will maintain the dash momentum.
  • While within momentum, charging in the air will not lock into a slow fall.
  • Return lever to neutral to break the dash jump momentum.
• Life extend at the following score thresholds: 50,000/150,000/300,000

Scoring System:

• Score on hit = [sum of yakus] x [charge multiplier]
• Level 0 attack -> x0 multiplier
• Level 1 attack -> x1 multiplier
• Level 2 attack -> x32 multiplier
• Level 3 attack -> x128 multiplier
• Yakus:
  • Base hit -> +20
  • Air hit -> +50
  • Clean hit -> +50

  • Enemy moving on hit -> +30
  • Enemy attacking on hit -> +70

  • Riichi -> +100

• Life bonus at end [Remaining lives x 50,000]

Riichi Mechanics:

• Press Up to declare Riichi.
• Cost 5000 score points to enter a Riichi state for ~8 seconds.
• Charging on ground AND in air can be Riichi-cancelled.
• Hitting the enemy,  getting damaged, missing the attack, or time expire will exit Riichi state.

  • Level 1 -> Increase damage by 1
  • Level 2 -> Gain knockback property
  • Level 3 -> Increase damage by 1 and charge multiplier increase to x256
• Upon exiting Riichi state, the player can Riichi again after scoring 42,000 more points
