Introducing wards!
What's that? A ward protects you from attacks, blocking 50% of damage (20% for bosses), consuming itself in the process.
You collect wards by killing enemies without being hit. Tough to do with normal enemies after the first few floors, but manageable with "slow" and "sluggish" modifiers (look out for them!). Wards are much harder to get later on, so you have to choose between rushing to the exit or collecting as many wards as you can on the first few floors. A fast completion depends on how well you can judge your typing ability ^_^
As for other development progress, I've finished the boss fight health bar and improved the UI all-round (although there are still some issues in builds). Now the game is almost ready for beta testing!
It's been a pretty productive week :)
