Hey Zack!
Thanks for playing my game! This feedback is very valuable and I will make sure to keep them in mind. Personally, I recommend you start playing the game on easy mode in order to get used to the controls and mechanics. Mouse sensitivity options are also available in the options in case you missed it.
In terms of progressing through the game, most people who played in normal mode had also said it was extremely difficult. So, its no problem if you didn't manage to get far :)
I hope you continue making these videos and achieve great success in the future!
