I really loved the Hard Hat series when I started, so I attempted to make a fangame.
Let me speak no more of it. It was a mess. The graphics were horrible, and gameplay was terrible. It was no fun at all, but the levels were somewhat fun to play through.
I intended for there to be 80 levels, and I only got 40 done... It was the first time I ever devoted myself to making a game. My math teacher in 7th grade even said I could bring the memory stick in for kids to try it. So I rushed to get it done...
