I just made a comparison worked in C2 than switched to C3 in the browser, than back to C2. C3 feels sort of fragile and some small stuff which I was used to in C2 is gone, like the expressions window is automatically opens up in C2, and in C3 it need an extra click. Plus tons of all these 3rd party plugins.
Overall the whole idea of subscription is a bad user experience, it scares off people. Guys, you would have sold way more copies till now for 200 - 300 € one payment + downloadable desktop, than what you have right now.
Please consider your user also in terms of product pricing and platform. Browser based and stuff is nice, why on earth should I pay you every year? Make a base software - one time payment, new updates/modules as DLC, if you need this new functionality - you buy it for extra price.
Free to play version of c3 is sort of alright, could be more events. Sorry, guys - bad marketing/price strategy.
AFAIK you don't work for Scirra so please justify the bold/underlined statement.
