Your tutorial has a section slight up top where everything including UI is hidden. Also broke it by dying there but I wasn't able to replicate it. Pretty fun but difficulty is too easy, I can run around in circles shooting the enemies and they couldn't hit me. Played up to wave 11 so I don't know if there are any more enemies besides the 3 I encountered but I like the designs. Saw a couple of power ups spawn outside the barrier where I couldn't reach but was the exception
