Between 3 and 3 1/2 hours to beat , I estimate. I lost a recording so not completely sure. I had to redo the first few areas to re-record them , so that would be part of the time too. Not sure if this game has selectable difficulties since its in Japanese. Just left it at default.
Decent game with some tedious and irritating parts , including the final boss if you dont position yourself right. I checked a speedrun to find the technique for the final boss.
