Hello! Just a post about a relatively small feature that I think will make a large impact to gameplay: construction time.Building instantly is no fun, so Harwell now has a fancy new construction shader which dynamically builds the building in sync with its construction time - Ooooo!This should add more strategy to when to place buildings - you have to be patient for your profits! Currently, all buildings will take 10 sols to build, but this may change after testing.In the future, I may improve this to add small cranes to construction sites or show some sort of under-construction texture.

Greetings! I'm Caleb, developer of Harwell. As part of update 0.18 Harwell got a huge update - actual, functional multiplayer, and it involved an ever so slight complete rework of the multiplayer system in the game. Here's what it entailed!Main MenuThe main change in the main menu is this new panel on the left side which displays your Steam and Nakama IDs and lets you update your display name:You'll also get a little setup screen when starting the game which asks if you want to link Steam to your Nakama account, if you click no it will just use Nakama and store a device ID which is anonymous b

Hello! It's Caleb, developer of Harwell. I decided to write a part two to my last development showcase, Building Modifiers. I've made some improvements and added some polish so this one is going to be much less technical and much more screenshot-ey.Tooltips!I've reworked and improved how modifiers are displayed in-game. As well as polishing the tooltip when placing buildings, the modifiers now show in the tooltips for construction buttons automatically, and also show in the building tooltips when you hover over a building (showing both the modifier, a description, and its effect).In terms of m

Development Showcase: ModifiersHello, it's Caleb, developer of Harwell. It's been a little while so I thought I'd write a festive write-up of what's been going on, and the most recent implementation in the game - building modifiers. Modifiers have taken some work to implement - having to build in JSON files, adjusting the building system, building them into the inventory system, and more. They're almost complete so I wanted to write a dev diary about the progress so far. I hope everyone has had a lovely Christmas this year!Updates to AISince the last update, I've been balancing the AI and conf
