Wow, impressive! Never seen someone manage to do that before!
The latest builds (so 1v82) have a few more space-saving tweaks which should help you squeeze a bit more out of it (~20%). There's still a little room for improvement, but yes - the level of memory available is such that it's entirely possible to write enough code that you'll run out of memory :(
It was actually a bit of a surprise just how much more compact minified code was - however the code used is quite maths-heavy and I'm sure you could find cases where minified code wasn't as good... but it does make you wonder what something like Web Assembly would really add.
