Added special monsters. There will be a chance to appear in the boss room from the beginning of the second round of the game.
New items:
Cosmic Energy Cube : Instantly absorbs all bullets on the field, creating an ultra-large energy bullet that deals 50% of base damage to the target every 0.5 seconds (each absorbed bullet provides 50% damage and increases energy bullet size by 5%, up to a maximum of 1000%).
Adjust the distribution of monster types in each level.
Removed cursed items from boss challenge mode.
v1.171
Fixed a bug where special monsters would not be able to cause damage to them if they were of a very high level.
