Working on item synergies has probably been the highlight of development for me while working on Against Great Darkness. Finding things that work well together is just a lot of fun. What keeps me coming back to play roguelikes are the interesting synergies that emerge during a run. Over the last few weeks, I've spent a lot of time revamping the relics you will find in the depths of hell.
Most of these items operate on a fun brick-breaking mechanic, which challenges you to keep those disks bouncing. Successfully juggling without losing a disk, or maintaining a set number of disks in play, will trigger some incredible effects.
Additionally, as the player, you are equipped with a set number of cleanses per wave. These cleanses are used to apply an upward force to all disks in play (so don't fret if you might lose out on a juggle if you have a cleanse handy!). But what they also do is clear all enemy projectiles on screen, which is pretty useful in its own right.
I thought it would be a great idea if the mechanic of the cleanse could be altered when you find certain items. One relic, in particular, will cause an explosion on every active disk when you use a cleanse! One of my favorite items is the Ouroboros; it completely changes the way you play. I'll let you discover what it does once you're in the game!
