Rift Riff now has a bunch of new levels to play! After releasing the game in May, we still had so many ideas floating around. I’m really glad we took the last four months to bring those to life. It now really feels like a complete Rift Riff. Please enjoy! #gamdev #godot #pixelart

We just released Rift Riff on Google Play and App Store, and I'm mega proud of the work the team did to get this running smoothly in #godot. The way the game has quick rounds, and how its interaction style is built, may (dare I say) even make it a better fit for phones than for desktop #mobilegaming

Is this too weird? (thread) #gamedev #conceptart

Is it important to do things that are easy and/or feel like a ‘fuck yeah’ in the early stages of designing a game? If I find something hard to understand, how will the player feel? #gamedev

An idea to add more height to an isometric building grid. Tiles behind other tiles won't be obscured as easily. Plus it makes it look way more dynamic. #gamedev #conceptart #godot

Trying out tiles. It does make it feel more tactile. But it also adds a layer betweeen the player and the fantasy. Instead of building a castle, you're playing a boardgame building a castle... #gamedev #conceptart

Sketch for an exploration phase, where you fly your floating-bunny-castle around, gather some spices, and visit a voodoo hut. Where you just try to get as much done as possible until your flappy-fish-hover-engine dies and the horrors of ground level come crawling up your fort again. #gamedev

Working on a builder interface. Trying to accommodate multiple interaction styles (keyboard, keyboard+mouse, gamepad). Some thinking in thread. #interface #gamedev #uiux

Vibe sketch for an encounter with a mythical creature. Floating dirt castle vs underground dragon? We don't know yet! #gamedev #conceptart #indiegame

Sketching a narrative introduction of why the game world is as it is. Player encounters an ogre, ogre aggressively chases player, player finds a cave to hide in, a blue rabbit lights up the cavern and starts levitating, ripping a piece of earth from the ground with it. #gamedev #conceptart #sketch

Started something new today. Curious to find out what this will become! #gamedev

Made animations for a new shop today (the module with the two test tubes hanging on the side of the platform). #pixelart #framebyframe #animation #godot

Added dirt patches to the grass for more variation, and boy does it make a difference! #pixelart #leveldesign #indiegame #godotengine

Added details to this environment. Workflow in thread👇 #gamedev #godot #pixelart

Rift Riff is getting a tree map! Blue trees! #gamedev #pixelart #leveldesign

I haven't really made a 'tree map' yet. Even though it's the most obvious thing to do in a tower defense game. It's pretty satisfying just placing trees everywhere I need obstacles. I can understand why people do it. #leveldesign #pixelart #indiegame #godot

Created an animation for the fire-breathing tower’s DoT effect — smoky blobs on affected monsters. Then tested it alongside all other effect towers to see how it holds up. The goal: making it clear when the effect is applied and has faded. #indiegame #pixelart #godotengine #gamedev

We're normally very professional. I promise. #contentupdate
