Demon Gate is an original HTML5 canvas browser game I built with vanilla JavaScript (no game engine). You get the complete project as a ZIP — ready to host, reskin, or embed on a client site.

What you get ✓ Full HTML5 + CSS + vanilla JS source ✓ 30 stages with bosses, ranks, and progressive difficulty ✓ Combat: combos, just-guard, soul absorb, elemental weapons, items ✓ Procedural Web Audio — no royalty-bearing music files ✓ Buyer docs: LICENSE, CUSTOMIZE guide, README ✓ Deploy anywhere static (Vercel, Netlify, GitHub Pages)

Perfect for • Indie devs learning canvas game loops • Agencies needing an interactive demo for a client LP • Portfolio builders who want a playable embed, not a video mockup

Tech HTML5 Canvas · Vanilla JavaScript · No framework · ~3.5MB ZIP

License Commercial use included for one end product. No resale/redistribution of the raw source as a competing asset pack. See LICENSE in the ZIP.

After purchase Instant file download. Need a white-label reskin, new stages, or Next.js embed? Message me — I offer scoped custom work + optional $200–400/mo retainer for updates.
