I’ve edited the pxtworker.js file under pxt-microbit\>node\_modules\>pxt-core\>built\>web\> At line 116592, i comment out the condition that checks too see if the program is too big: I then edit it to show me a bit more information. With that being said, I’m finding there are around 23K available out of a possible 242K of program space. What this implies (to me) is that we a…

From my findings, it appears the base code takes around 91% of program memory ever with a blank project (on a V1.x micro:bit). I’ve been looking for ways to reduce memory size while maintaining core functionality for students using it.
