Infernal UI Lite - Free Hell & Demon Pixel Art UI Kit

The full pack, Infernal UI: 1,099 sprites, 481 icons and 7 example screens for $4.99

Infernal UI Lite: a free hell-and-demon pixel art GUI kit

Obsidian and stone with lava seams, brimstone and ember accents and demonic sigils (no gore). Plain PNGs, made for a 960x540 screen (2x is pixel-perfect at 1080p), and they work in any engine: Godot, Unity, GameMaker, Defold, Phaser, RPG Maker, LOVE.

What is in the free zip

• 127 sprites (48 elements), at 1x and 2x
• a window with title bar and sigil corners, a card, an inset panel, a tooltip and a divider (9-slice, insets in manifest.json)
• the stone button in 2 sizes and 7 states (idle, hover, pressed, focus, selected, selected + focus, disabled), plus close and settings icon buttons
• a checkbox, a toggle and a slider
• a bar with red, blue and green fills, and pips
• the 32 px slot in 9 states
• 24 icons at 24 px, each with a disabled version
• free fonts and a short LLM_GUIDE.md so an AI coding assistant can use the kit correctly

A complete small kit, not a crippled one: you can finish a real menu, settings window or inventory screen with it.

This settings window uses only Lite sprites: the window, sliders, a toggle, checkboxes and stone buttons, with their focus and pressed states.

A small inventory, a character card and a menu, again only Lite sprites: slots in their states, a tooltip, bars and pips.

The window, card, tooltip, button and bars are 9-slice: one sprite stretches to any size.

Licence (summary; full text in LICENSE.txt)

• Use it in any number of personal and commercial games, apps and videos. No royalties; credit is appreciated, not required. Client work is fine.
• Modify, recolour, crop, animate and combine the sprites freely.
• Do not resell or redistribute the sprites as assets, packs or templates, or upload them to public repositories or asset stores.
• Do not use the sprites to train, fine-tune or evaluate generative AI models.
• The fonts are third-party and keep their own licences (OFL 1.1 and CC0, in fonts/).

How it was made: an AI-assisted pipeline: AI image generation for the base art, then code for the pixel clean-up, states, 9-slice geometry and manifest; the code and docs are AI-written too. Every sprite was checked at 1x and zoomed in, and is 100 % on the palette.

Install instructions

• Unzip Infernal_UI_Lite_v1.0.zip. Use 1x for a 960x540 screen and 2x for 1080p.
• Use nearest-neighbour filtering with mipmaps off, and keep positions on whole pixels.
• 9-slice insets (left, top, right, bottom, in 1x pixels) and fill modes are in manifest.json; pieces/ and presized/ help engines without 9-slice support.
• Coding with an AI assistant? Start it from LLM_GUIDE.md.
