Based on the feedback we received at the GDC from partners and friends, we know that we need a way to reduce the size of our exports. Currently, the 4.3 release Web build .wasm is around 40 MB uncompressed, and 5 MB compressed with Brotli. We have a few ideas in mind to address this, and it could even help optimize builds for other platforms!

This is very exciting! It’s my #1 issue by far with the engine. With custom export templates I managed to keep it around ~25MB uncompressed, but there’s definitely a lot of room for improvement in binary size.
