I built a full pinball game that runs inside Reddit — feedback welcome

/u/Successful-Ad-5576 Reddit r/webdev 2026-09-13 04:33 4 views

I've been working on Pinball King Karma, a full pinball game that runs directly inside Reddit using Devvit Web.

Play it here:
https://www.reddit.com/r/pinballkarma_dev/comments/1s2twov/pinball_king_karma_play_now/

The current stack includes:

HTML5 Canvas
Box2D / Planck.js for physics
CreateJS for rendering
Hono + Reddit Redis for scores and leaderboards
Keyboard and mobile touch controls

I've added multiball, jackpots, multipliers, daily challenges, community leaderboards and karma-themed bonus modes.

One area I'm still working on is making the physics and controls feel as good as possible across desktop and mobile.

I'd especially appreciate feedback on ball physics, flipper responsiveness and mobile controls.

Built as a side project while experimenting with what can be done with Reddit's Devvit platform.

3 Ways I Use AI to Auto-Generate Playwright Locators

If you've maintained a Playwright suite for more than a few months, you know the real cost isn't writing tests — it's the constant locator rot. A designer tweaks a class name, a component gets refactored, and suddenly a dozen tests are red for reasons that have nothing to do with actual bugs. After
