Tough Luck

Tough Luck is an ingame system, randomly placing new mechanics in levels. At the beginning of a level, an effect may be selected from the list.

Effects

 * Quadruple Trouble: An additional monster chosen for the level, bringing the count up to 4. Lesser enemies will not appear.
 * Culling of Loot: The more common and lower tier loot will be removed and exchanged for a smaller amount of rarer loot.
 * Twinsies: Only two different monsters will appear on this level, but there will be two of each.
 * Super Monsters: Only two different monsters will appear, but each are guarenteed to be top variant monsters.
 * XL: The floor is larger, and there is an additional monster and more loot.
 * Tight: The floor is smaller, the only upside is that there is the same loot as a regular stage, but just packed tigheter together and thus more easy to access.
 * Slow Zone: There are twice the amount of monsters, lesser and otherwise, but they all move, attack, etc. at half speed.
 * You're too Slow: Game runs at double speed, everything happens twice as fast. There is also slightly more loot.
 * Pain and Gain: Everything does double damage, both you and your enemies. There is also slightly more loot.
 * The Calm: Recieve a one minute grace period of no enemies at the start of the level. Once it ends, half of all loot left on the level will vanish, and 4 monsters will appear.
 * Be a Hero: One of the enemies will hold the keys for the exit. You will be forced to kill that one if you want to leave. It will be indicated by a small gold sparkle around the enemy, and killing them will not count as murder and interfere with passifism and related unlocks. There will also be much more loot than usual.
 * Allergies: Every 30 seconds, you will sneeze, producing a loud noise that may alert monsters to your pressence. Planning accordingly will be key. Lesser enemy populations will be reduced, and slightly more loot will be present.
 * Silent Night: Nothing will make any noise. You can run around without making a sound but the monsters could be silently lurking around any corner. Loot is slightly reduced.
 * Spyman: There are 5 monsters, but you can see their sillouettes through walls. Sneak appropriately.
