Very neat! I don't know exactly how "from-scratch" you built this, but I'm guessing "very", and that's pretty impressive, gotta hand it to you. It did take me a little while to figure out what was going on. I'm not sure if this was intentional, but it seems like some of the buildings were spaced pretty far apart from each other, so I ended up not killing enemies and waiting so that I could use them to help me jump longer distances. Whatever that creature is that is chasing you is pretty terrifying.
Nitpicks:
- I wish the game didn't close itself on losing, it's a bit of a buzzkill to not see what your score was when you lost
- I know Tori would kill enemies for me, but I don't think I got score for it... doesn't that kind of make Tori a bad thing?
