Built on a pure rules class fed by a small event bus.Sun, 18 Oct 2026 00:00:00 GMThttps://alvarofalcon.github.io/devlogs/arpg-game/rift-progression-and-ux-passes/https://alvarofalcon.github.io/devlogs/arpg-game/rift-progression-and-ux-passes/A run of owner-driven polish: cursors, loot key, town walks that don't get stuck, a town map, a Rift level-up cadence with per-card rerolls and pending items, instant tooltips, Odran's gem shop and a Colossus cash-out decision.Sun, 18 Oct 2026 00:00:00 GMThttps://alvarofalcon.github.io/devlogs/arpg-game/caverns-spawning-and-drops/https://alvarofalcon.github.io/devlogs/arpg-game/caverns-spawning-and-drops/Realities stopped being rooms linked by corridors and became steered cellular-automata caverns with one-piece rock walls and real liquids; spawning moved to Poisson-disk packs and a Rift director; item rarity became a cascade.Thu, 15 Oct 2026 00:00:00 GMThttps://alvarofalcon.github.io/devlogs/arpg-game/monster-scaling-mass-deaths-and-the-tree/https://alvarofalcon.github.io/devlogs/arpg-game/monster-scaling-mass-deaths-and-the-tree/Monsters now scale from a measured reference character and a time-to-kill target, a benchmark found that voxel crumbles (not explosions) caused the frame drop when packs die, and the passive tree grew from 92 to 339 nodes.Thu, 15 Oct 2026 00:00:00 GMThttps://alvarofalcon.github.io/devlogs/arpg-game/crafting-a-merchant-and-a-town/https://alvarofalcon.github.io/devlogs/arpg-game/crafting-a-merchant-and-a-town/Nine original crafting orbs, Odran the trader, the Artificer's forge, item art, and an empty hideout room that turned into a walled town with an edit mode, a shop and a HUD that explains itself.Tue, 13 Oct 2026 00:00:00 GMThttps://alvarofalcon.github.io/devlogs/arpg-game/endgame-and-persistent-characters/https://alvarofalcon.github.io/devlogs/arpg-game/endgame-and-persistent-characters/The survivor run worked, so the next question was where the game really lives. We pivoted to a map-style endgame: Mirror shards open Altered Realities, characters persist with a passive tree, gems and ascendancies, and a new character learns it all in a short introduction.Mon, 12 Oct 2026 00:00:00 GMThttps://alvarofalcon.github.io/devlogs/arpg-game/voxels-anime-heroes-and-a-hud-of-your-own/https://alvarofalcon.github.io/devlogs/arpg-game/voxels-anime-heroes-and-a-hud-of-your-own/In one day the game got a voxel HD-2D presentation under an unchanged 2D simulation, anime-style characters at double resolution, a renamed repo with a self-updating launcher, flasks and a HUD the player can drag and resize.Mon, 12 Oct 2026 00:00:00 GMThttps://alvarofalcon.github.io/devlogs/arpg-game/the-survivor-run/https://alvarofalcon.github.io/devlogs/arpg-game/the-survivor-run/Until last night, ARPG Game was a very well-tested sandbox: a mage, some training dummies, a fireball with forks, an affix system, a grid inventory. Every system was there; nothing to do with them. This post is about…Sun, 11 Oct 2026 00:00:00 GMThttps://alvarofalcon.github.io/devlogs/arpg-game/inventory-and-the-playtest-bugs/https://alvarofalcon.github.io/devlogs/arpg-game/inventory-and-the-playtest-bugs/The last post ended with equipping working but no screen to do it from — auto-equip-on-pickup, a bridge explicitly labelled as scaffolding, standing in for the grid inventory that didn't exist yet. This post is that…Thu, 10 Sep 2026 00:00:00 GMThttps://alvarofalcon.github.io/devlogs/arpg-game/affixes-and-equipping/https://alvarofalcon.github.io/devlogs/arpg-game/affixes-and-equipping/The last post shipped the drop pipeline with currency alone, deliberately: prove the seam with gold piles before building anything equipment-shaped on top of it. This one is the payoff — base items, the affix system,…Wed, 09 Sep 2026 00:00:00 GMThttps://alvarofalcon.github.io/devlogs/arpg-game/items-and-currency/https://alvarofalcon.github.io/devlogs/arpg-game/items-and-currency/The last post ended with a fireball that could fork, pierce, and fan into a spread. This one is a step sideways rather than forward: before a single item can drop, something has to decide what a "item" even is — and…Tue, 08 Sep 2026 00:00:00 GMThttps://alvarofalcon.github.io/devlogs/arpg-game/movement/https://alvarofalcon.github.io/devlogs/arpg-game/movement/This is the first devlog for ARPG Game, a 2D top-down action RPG in Godot 4.1.1 built in C#/.NET. Before this session the repo had nothing but scaffolding — and the interesting part was everything that went wrong while trying to see it work.Mon, 07 Sep 2026 00:00:00 GMThttps://alvarofalcon.github.io/devlogs/arpg-game/skills-and-combat/https://alvarofalcon.github.io/devlogs/arpg-game/skills-and-combat/The last post left off with a shape that could walk around a grey rectangle. This one is the direct sequel: that shape can now cast a projectile skill, the projectile can hit things, the things can die, and the skill…Mon, 07 Sep 2026 00:00:00 GMT
