Around 2 hours 3 minutes to beat (1 hour 36 according to Clear Screen). There was also 11 minutes wasted on replaying a stage twice since it crashed out on the exact same part twice. That wouldve put my estimate at 1 hour 52 minutes, pretty close to the clear screen time. It probably doesnt count pause screens, so may be accurate.
This is unedited but I left out one of the crashed attempts on the alien stage. I do show the first crash, and going back out to the title screen to restart the stage. I had to uninstall the game and re-install it to get it not to crash there.
Planning to work on Hard Mode and maybe see about the 1 hit death setting. Might do that on Normal first. Ill post up whatever I complete. I should have a playthrough of the Switch version up soon too.
Really enjoyed the game overall. The desert stage felt a little sloppy to me, getting hung up on ledges, but the rest of the game felt great.
