First off, I hated jump king and couldn't get past the first few stages. I probably hated it because I was shit at the controls. I was able to beat getting over it, because the controls were easier to master. Jump King had really good art and atmosphere though, so I was pretty desperate to get to the top to see all the art. I guess you managed to replicate the controls, but there isn't really a reason to want to go to the top like in jump king, which is why I rage quit just a few minutes in.
