SigilCraft
Your Spell-Engine has awoken.
In Sigilcraft, Crafters are tasked to master the art of glyph arrangement, elemental synergy, and magical growth through the refinement of the alchemical arts. Hone the spell grid within these pages and weave fate through your will, young Architect. Optimize this spell engine to manifest the reality to grow the library that is is the foundation of the mind. Discover your elemental attunement and master reality your way.
Features
-
Spellbook + "Excel Sheet" UI — Play inside a minimalist mystical grimoire with parchment textures, leather tones, and the impressions of academia.
-
Elemental Glyphs — Use the elemental primers to form continuous magical effects.
-
3×3 Spell Grid — Draw, stack, and apply sigilized patterns to cast spells, unlock sequenced ritual patterns for even greater enchantments.
-
Buff System — Each glyph grants passive boosts; experiment with layouts to maximize power. Evolve your grimoires by maximizing your placements.
-
Alternative Progression — No traditional prestige; instead, explore "endgame" through the graduation of grimoires, granting Architects mastery-level bonuses and effects.
-
Over +100 Features to Discovery — Unlock new glyphs, essences, and casting methods as you grow the Engine. A variety of mechanics to establish your own playstyle. Will you discover all of your capabilities?

This has a lot of potential and I've had some fun, but I've also found some bugs:
Sometimes the spellcasting area requires you to pick a different spell and come back to the original in order for it to recognize the pattern.
The Grimoire Spell-Engine will sometimes just randomly make it so that you can't see any glyphs when you click on Manifest Glyph - I've tried saving and refreshing the page, but the only thing I know works is resetting the game.
Thank you so much for playing, and I'm glad you had fun! I also appreciate the feedback. Having to reset the game because of bug sucks, I'll take a look at it and see what I can do in the next update!
