-this year for roguelikedev does the complete tutorial, i'm following along with thebracket's [_roguelike tutorial - in rust_](https://bfnightly.bracketproductions.com). for most of the 8 weeks, i'll probably just be working through the content rather than diverging too much into doing my own thing, since it's lengthy and i'd rather finish in time. that said, the ultimate aim here is to strip out the vast majority of the existing entities and replace them with my own, using the systems and components from the tutorial as a jumping-off point for something of my own making.

+## v0.1.4
+### added
+- **overmap**: bare, but exists. player now starts on the overworld, and can move to local maps (like the old starting town) via >. can leave local maps back to the overmap by walking out of the map boundaries.
+- **intrinsics**: speed, regeneration
+- **damage types**: immunities, weaknesses, and resistances
+- **full keyboard support**: examining and targeting can now be done via keyboard only
+- **a config file** read at runtime, unfortunately not compatible with WASM builds yet
+- **morgue files**: y/n prompt to write a morgue file on death to /morgue/foo.txt, or to the console for WASM builds
+- **dungeon features**: just the basics so far. a grassy, forested treant room, some barracks, etc.
+- **named maps**: "Town", "Dungeon"
+- **map messages/hints**: "You hear <...>."
+### changed
+- **colour offsets** are now per-tile (and per-theme) instead of +-% globally. i.e. varying fg/bg offset on a per-tiletype basis
+- **chatlog colours** are now consistent
+### fixed
+- negative starting mana
+- status effects only ticking if mob turn aligned with turnclock turn
+- map params not being saved on map transition
+- mob turns not awaiting the particle queue (mobs moving around mid-animation)
+- mobs not re-pathing if their path was blocked, causing traffic jams

@@ -46,5 +46,10 @@ Complex example, with negative AC:
 - At worst (AC rolls a 14), the monster must roll less than -1 to hit you. Impossible.
 - It rolls a 9, and your AC rolls a 2. 9 is less than 11 (10 + 3 - 2), so it hits.
 - It rolls 1d8 for damage, and gets a 6.
+bloodstains: if starts on bloodied tile, remove blood + heal, gain xp, grow (little dog -> dog), etc.
 - You have negative AC, so you roll 1d14 for damage reduction, and get an 8.
 - The total damage is 6 - 8 = -2, but damage can't be negative, so you take 1 point of damage.

+tl;dr
+1. Lower AC is better
+2. Aim for 0 AC - it's an important breakpoint. Every point of AC before 0 counts for a lot.
