Hello,
Seeing as you've made the software free, will I get the money back? I acquired the software back when it was required to pay for the software... and though I felt it was worth the money at the time, it hardly seems fair that I had to pay for something that is now free.
Thanks, 
Nicolas

I paid for it too, but I wouldn't want to have my money back, it was released almost two years ago and it's the work of a solo dev. You paid not just for the product but also for the production.
I'm happy it's free and more people can play this

plus it was like 5 dollars :)

I paid $15 after it was made 'free'. I paid what I felt it was worth, and you said yourself that it was worth it to you.

Hey, I paid full price for Team Fortress 2 as well as like CS: GO and they became free!

This game is worth at least 10 bucks. You're lucky if you got it that cheap back then ;)
