Customer Feedback: Martian

I tried the free option it works great. In case in the future you might want to remove the free option (which is understandable), can I suggest for you to introduce a credit system like the one on exaroton? Where you pay for hours/days, instead of months. I don't mind paying but I don't want on a per-month basis. Exaroton is very cool for doing this system but I heard their performance is shit.
