It is because of this line https://github.com/espruino/Espruino/blob/master/boards/PUCKJS.py#L71 , when disabling all optional stuff you can probably double that. With just bluetooth and graphics libraries enabled (see few lines above) I have this set to 30 e.g. in build for P8 smartwatch.
If you still need much more maybe you can put SPI flash chip inside? They are cheap and small. Not sure how much space is there but thanks to banglejs the SPI flash is now well supported as main storage so if there are spare 4 i/o pins it could work . Bare chip would do too or some small module like https://www.aliexpress.com/item/4001174857221.html can give you up to 16MB for < $2
