I built a 150kb game with my custom JavaScript engine that runs instantly in any modern web browser at 60 FPS - quick gameplay trailer
I've been building NULLFRAME for about a year. It basically started as a free browser game inspired by Superhot and Super Meat Boy, but after a year of development in my spare time I think it's turned into something pretty good.
One thing I'm quite proud of is that it's built 100% from scratch with my own engine, written entirely in vanilla JavaScript - no frameworks or third party engines. The whole game weighs in at around 150kb and all graphics and sound effects are dynamically generated via code. There are no sprites etc and I think it gives it quite a unique look and feel.
It runs instantly in any modern browser at 60fps (provided you have a reasonable CPU) and there's a map editor where you can create your own challenges and share them instantly via a URL - the map data is all encoded into the URL using my own custom compression system, so nothing is stored on the server. My friends have been experimenting with it for a few months and say its great fun.
As mentioned, gameplay borrows elements of both Superhot and Super Meat Boy, though I like to think it has its own style. Gameplay requires careful strategy, but it also allows you to enjoy some carnage from time to time too.
I'm planning on releasing for free later this year. I'm a dev of 25 years, and nowadays I basically just build the odd game for fun. I think possibly it has some commercial appeal, but I have no idea about marketing games.
Just to clarify:
- the anime intro was produced by a commercial animation studio specifically for the game (I know people get suspicious, so wanted to be clear).
- trailer music purchased from AudioJungle
- Some additional ambient effects in the trailer sourced from Pixabay and then modified by me.
