Around 9 hours 12 minutes to beat both required loops. The game requires it to be beaten twice for the true ending. This is a VERY shitty port. I will probably go more in detail in a review of the game soon. It plays very badly, which is the main challenge. Its more of an irritating game then a hard game, execution wise. You repeat similar patterns until you break through, once you have a path. The original arcade version took me 2 hours longer to beat, but played MUCH better. That version took longer due to legitimate challenge.
The 6th stage of the second loop was the hardest part, taking around 3 hours 42 minutes. The second loop is a little harder which can make a difference when the game plays so bad to begin with. The entire first loop only took me around 3 hours, so the game wasn't too difficult for me. I took some breaks so I wasn't playing consistently.
I show the first death at each new checkpoint, but the rest of the deaths are edited out. This game has infinite continues. Full tutorial with commentary coming soon.
