Now, this kinda works on mobile devices as well (android/iphone/ipad) by just surfing to the particular page, but I guess a dedicated app would work better / be more convenient on these devices.
I have exactly zero experience developing for iOS or Android, so maybe this question is too complicated to fully answer right away, but:
Is it possible to create an app for Android, and similarly for iOS (iphone/ipad), based on my html page, other than basically rewriting the entire game for those particular platforms?
If yes, how do I go about this? What would be the easiest way? Is there a ton of Android / iOS knowledge required, or is there some kind of generic “conversion” that wraps my html page (+required images) into a mobile app?
I guess that phonegap would perfectly fit your needs.
Hope it helps
Appcelerator can do that. It builds native Android apps and iOS. The language is based on HTML5 and JS so I think it can help you.
I recommend you to use construct 2. It has better development tools for HTML5. Here is a link to construct 2 website.
