Level 8 is (deliberately) pretty tricky! I didn't want players to just breeze through every level of the demo ;-) Might make a couple of changes to ease things up just a touch in the full game. I hope people don't play it and think "if 8 is so tough then later levels will be impossible..." The difficulty won't go up every single level.
Thank you so much for taking the time to play the demo and make a video :-)
