Hypersplit is like Neal's Infinite Craft but turned upside down. Instead of crafting your way up from the four elements, you start big and go small, down to quarks.<p>It's using GPT-4 to split the words, but a big difference from Infinite Craft is that I can precalculate the possible paths since they are limited (sooner or later you hit a quark or a loop). This means that I can ship it with the whole dictionary locally instead of hitting an LLM every split.<p>While it started with just the splitting, I quickly got the urge to split things faster... which turned the app into the incremental clicker it is now. It's pretty short and starts lagging a lot once things get crazy with a lot of chain reactions (turning off Effects helps a bit), but I plan to focus on optimizations next.<p>I also wanted to try and build something without any graphical assets. The whole game is all just emojis and CSS. A big gotcha is that you can't rely on emojis looking the same on different platforms (for example, on Windows, the explosions are misaligned).
