Due to lack of time we weren't able to expand upon the gameplay, but thanks for trying it out anyway! By the time we noticed the subpixels, we were pretty late into the jam and sadly weren't able to come up with a solution in time. And the web build was made with Emscripten and its built-in SDL2 port, which has worked well in the past but seems to be unstable for this specific game since we use a lot of dynamic memory (de)allocation.
