Dead Ringer stacking added - if you complete a tenth stage while already holding a Dead Ringer, you're given another (visualized on the hud). When you die with multiple, you use up one.

Hud element for Dead Ringer invincibility with a visual timer for how long it will last

Slightly reworked the enemy pool - difficulty remains the same, but overcrowding and bad rolls should be less of an issue now (don't worry, I playtested)

ARG Man can now rarely spawn in the previously deprecated 4th enemy slot. Currently he is the only enemy that can use this slot, but that will likely change as more 'complimentary' enemies are added in the future
