Hi everyone reading this!

Let me begin with a bit of information about myself. I started IOS developing last year November. I wanted to make a game like trainyard express and I came up with Monster Catch. I need alot of direction as im quite lost

Problem 1)
Now i am pretty sure this isn't a terrible game but after about 4 days of selling i had 100 sales for lite and 4 paid..Yes thats right.4 sales. I have had no sales since and i am a bit lost about what went wrong

Problem 2)
I tried getting into contact with about 10-15 reviewers however only one (Applicious) has replied and offered a deal for $750 which i didnt do.

TLR-
Is my game terrible?
Why have my game sales gone dead flat? Why is my app so invisible?
Does my icon suck?
Why does no app reviewer respond to me when i try get in touch with them? Is there a secret to it?

Thank you all for reading!
