I’m building a light-hearted, pick-up-and-play PvP game where players fight with anything but the usual guns and knives. The core idea is simple: small teams drop into compact, purpose-built arenas and scramble for randomly spawned items—rubber chickens, enchanted brooms, exploding soccer balls—anything that feels quirky and fun. Matches should stay quick, chaotic and above all casual. Match Formats The game must recognise three queue options and load the correct map layout automatically: • 1 v 1 • 2 v 2 • 3 v 3 Arena System Each format gets its own self-contained arena. I’m open on visual style for now, so feel free to propose an art direction that suits a playful, non-violent tone. What matters most is tight level design that keeps pla...

I print 4–5 m cotton lengths every day with a single colour. Right now I block-print each piece by hand with wooden stamps, lifting, realigning, and stamping the fabric five times before rolling it forward. The manual cycle is accurate but far too slow, so I want to replace only the stamping phase with a faster, low-cost, semi-automatic alternative based on screen printing. Here is the workflow that must stay: I will still feed, tension, and roll the fabric manually between passes; patterns change daily, so the tooling has to let me swap a screen or frame quickly without expensive re-registration steps. Key goals • Screen-printing mechanism that repeatedly places one top motif and four-to-five evenly spaced repeats in a single travel. • Compact footprint suited to a s...

I’d like a high-fidelity interface demo built in Figma ( is fine if you prefer) for a forthcoming web application. The primary objective is to showcase polished visual aesthetics that mirror the brand guidelines I’ll share with you at kickoff—logo files, color palette, and typography are all ready to drop in. You’ll receive a concise feature outline and a few user-flow sketches; from there, translate them into clean, responsive screens that feel modern yet consistent with the brand. I’m after realistic styling rather than wireframes, so please lean on components, auto-layout, and smart prototyping to bring the pages to life. Deliverables • High-fidelity mock-ups for each core screen (desktop first, tablet/mobile variants appreciated) • An inter...

Along the way, I expect attention to performance profiling so the build stays smooth on mid-tier PCs. Deliverables: • A standalone prototype build showcasing one short level,...

I’m building a mobile-first social networking platform and need a complete UI/UX treatment that feels clean, modern, and instantly familiar. Simplicity, usability, and clarity are non-negotiable; every screen should guide users intuitively through profiles, messaging, and a dynamic feed without cognitive clutter. Here’s the flow I have in mind: you’ll begin with quick wireframes to lock down information architecture, iterate into high-fidelity screens, then tie everything together in an interactive Figma prototype. I’ll provide the brand palette, logo, and core feature list—your task is to translate them into delightful visuals and micro-interactions that keep users engaged. Deliverables (all in Figma) • Low-fidelity wireframes covering onboarding, feed...
