I laughed out loud when I realized that I needed the blood machine. This was a charming and fun game, and really fun to play. A nice twist on the shoot to move genre. And thank you so much for having checkpoints.
Only issue I had was when the level loaded the coord for the machine would go crazy, and one shot could send it flying and kill me immediately.
And I assume the end of the game is when I can just walk out into the empty void?
Either way, super good job and great concept and execution!
