Minor Update

Quick update, mostly bugfixes but a couple cool new things too!

Bugs Squashed:

• Fixed bug with keys being left on stairs by fast minions while in fast-forward (thanks to everyone who reported this!)
• Duplicate cards being shown in the store
• Dying minions not dropping their items until after their death animation plays (this could cause a later minion to pass over without picking up a dropped key)
• Minions could in some cases be killed while exiting on the stairs

New Features:

• The store now has a reroll button! It costs 1 coin to start, but increases by 1 coin every time you use it.

Tweaks:

• Adjusted particle effects to be a bit less obnoxious
• Added extra keys on floors 7 & 4
