I tried this out, but unfortunately, it doesn't work for my needs, mainly because of the GameMaker requirement. I know I tried GameMaker once in the past, but their pricing system and app has gotten a lot worse since then.
Sadly, a key feature of the game idea I had is frequent updates, and due to the fact that GameMaker requires subscriptions to publish anywhere other than Opera's proprietary system, with the subscription prices as high as $79 per month for publishing to console, it's just not practical.
MonMae itself is well-designed, but personally, unless this becomes stand-alone or gets ported to something like Godot, I'm going to have to look elsewhere.
