Hello, Even if I try to use the command: node /usr/lib/node_modules/dexcalibur/dexcalibur.js --max-old-space-size=16384 I still get the crash with error JavaScript heap out of memory:

ok the only way I have made it work is modifying the file: /usr/lib/node_modules/dexcalibur/dexcalibur.js and add:

#!/usr/bin/env node --max-old-space-size=16384 to the shebang. I needed to use this otherwise dexcalibur launch node without the option. I tried to play with option in file: /usr/lib/node_modules/dexcalibur/dexcalibur but it never worked.

hi,

did you try

node --max-old-space-size=16384 /usr/lib/node_modules/dexcalibur/dexcalibur.js

instead of

node /usr/lib/node_modules/dexcalibur/dexcalibur.js --max-old-space-size=16384

?
