Minimal Crosswalk App is now 17MB, leaving you 33MB for your game. For the extra assets one possibility is using a free CDN service and then it could be totally under your control, just use pure HTML5, and work the same on non-crosswalk platforms.

Any news if this is still the same?
.... that is way too much overhead when iOS and Android Store has a 50MB limit on apps. That means our apps definitely need to be 25MB or less, which limits what you can realistic make. Big studios have fileservers and teams to streamline out-of-store downloading of assets so some games are hundreds of MB or even a GB..
