Around 31 minutes to beat this final stage of the first loop. Difficult because of the shitty controls and choppy scrolling, but otherwise not too bad for me. I am accustomed to much harder games. Even the arcade version was quite a bit harder taking around 7 hours for the first loop. The first loop of this shitty port took around 3 hours. Its not as dense and aggressive as the arcade version but the controls are so unresponsive it adds a shitty type of challenge. Legend mode in the new Ghosts N Goblins Resurrection is insane though. If I get back to that one, it will take me a while.
I will see if this second required loop is much harder in the later stages. Then I can give my full impression on the difficulty of the game. The first stage was a lot harder, with the shitty controls, so I will find out soon. I don't think its anything that will slow me down massively. I've been playing this game on and off but may go for the kill now.
A full tutorial with commentary for both loops will be posted up once I finish the game.
