Two problems, One: the sensitivity of mouse is very few, Two: When you finish one level, you can't click in "Next level" because you don't have mouse. but for the rest It's a good game :D!
I think the sensitivity is okay because you don't need to look around all that much(it's even possible to complete the entire game without using mouse!), you know you can use "L" to unlock mouse right? Anyways I'm glad you liked the game and Thanks For Playing
