In addition to bugfixes, we found that many players were struggling more than anticipated, so we are introducing an iframe after taking damage to make it a little easier to recover from a mistake. On Normal, we made it a bit easier to regen HP. Also, Demon fog tweaks.

Balance Changes:

• The player now is invulnerable for the next beat immediately after being hit.
  
• On Demon, player fog and lane fog are no longer ever active at the same time.
  
• On Normal, player regains HP every 5 notes in a combo instead of 10.
  
• Grading system has been adjusted and is basically the American school grading system.
  

Bug Fixes:

• Fixed various leaderboard UI bugs
  
• Disabled pausing via alt-tabbing during scene transitions
  
• Progress not saving should be fixed (please make a discussion post if it is not)
