I couple of weeks ago I purchased Game Maker Studio, after buying Professional for $99 dollars 1 day after I decided to buy the HTML5 export for $199.00. I realized that after 3 days I have spent $299 and Would actually need to export to iOS and Android. I didn't want to spend the $500 from the beginning because I wanted to try at least one export. So after 3 days I wrote to Game Maker support to see if they could honor my purchase and allow me to buy the Master Version for the difference, after all, I bought the others just 3 days ago. I didn't want to feel like an idiot spending another $500. They didn't care, they expected me to spend $800 dollars for what others would pay $500. I could not make myself pay these obscene amount for it. A couple of days later I discover Construct 2. Wow! Not only I was able to do in 1 day what would take me 3 days to do in Game Maker, but the cost of getting a full featured solution was good enough for me to pull the trigger immediately.
I have to add, Construct is far better anyways. Just one word is enough to realize this "Layers"
Thanks SCIRRA!
