Personally, I had totally no idea about HTML5 technology and its state, and still I don't want to know about that. I just wanted to make some game apps for my friends. I bought C2 for some silly reasons : I'm used to making maps with Blizzard map editor(similar with event sheet system), the community was nice, it was on sale, the design of the website was cool, and that cool website said "You can export your game in mobile. Android, IOS, etc, but you only pay once." After purchase, I come to know that exporting for the mobiles is not that easy thing. Bugs and fps drops were everywhere.
A year passed after purchase, and still I didn't learn how to code, but thanks to community, I learned many tips. There's STILL many hard things with mobile exporting, but I don't regret my choice for some glitches about those performance/exporting issues, because it's just for my hobby.
