Batch Processing: how I reduced CPU overhead by 99.5% in Unity
Working on tower defense optimization. Initial state: 64 FPS, game lags at wave 7.
Opened Profiler - found the problem: 11,900 Update() calls per second.
Every Enemy, Tower, Projectile, StatusEffect had its own Update() method.
The Problem: 500 enemies × Update() = 3,000 calls/sec 600 towers × Update() = 3,600 calls/sec
1,800 effects × Update() = 10,800 calls/sec Total: 11,900 calls/frame
The Solution: System-based architecture
Instead of 500 individual Update() → one MovementSystem.Tick() processing all entities in a single pass.
Results:
Update() calls: 11,900/sec → 50/sec (-99.5%)
CPU time: 15.6ms → 6.9ms (-56%)
FPS: 63.9 → 144.1 (+125%)
Key takeaway: Batch processing beats individual updates 20× in performance.

My Submission for #GameswithRive challenge.
You control some battery juice tryna dodge a thirsty robot named Robby! 🤪
Wanted to make a simple game based on cursor tracking.
Some features I could add:
1. Robby has 2 power ups- a size buff and ability to create clones (yes I wanted to give the enemy some power-ups for a change!)
2. Apart from this the general difficulty increase with time as Robby gains speed
3. Wanted to add some Game juice as well, so when you dodge very closely, the battery releases sparks
4. Robby's eyes are always tracking the player (well he's thirsty ofc!)
Plenty of improvements still exist but I am glad how this turned out right before the deadline! 😇

Dope
I built a small game for designers called TapTrap.
It’s inspired by those old school “Tricky IQ Test” games, but redesigned for people who obsess over alignment and argue about hex codes for fun.
I actually started building it before scripting was available in Rive, so most of the timers were powered by events and some pretty tangled state machines. When scripting finally came out, it helped me clean things up and make the whole thing work the way I had imagined.
It still needs some polishing and love, but I just could not keep this hidden any longer.
Unmasked,
An imposter-themed party game that tests trust between friends. Unmasked uses the smartphone as a central part of the game, with no downloads required: just scan, log in, and start to be suspicious.
Local winner of the Global Game Jam 2026 and made from idea to playable multiplayer game under a 48 hrs window.
The game was built using Unity, Rive and the backend was made in Node.js with Socket.io Leveraging heavily on Rive and its useful tools like data-binding, state machines and scripting, for a rich animation experience in which the user can see they avatars changing in real time.
Still not done with the game, currently working on using Rive for all of the UI, plan to release it publicly once it’s all done.
Hope You all like my entry for the Games with Rive Challenge.
