This game is great! But I've encountered a bug where all lights started flickering. I suppose that should only be in the house but it gets annoying so you have to quit and restart. Other than that it's a tad easy. I beat both bosses first try. Gascoigne even without any upgrades. I know you won't continue work on this game but this is a nice proof of concept.
I got that bug once or twice too, but never figured out what caused it. Basically, the lighting system tries to shift from one color of light to another, but can never land on the new color, cycling through a bunch of RGB values to try and hit it.
Next game / if Yarntown becomes its own IP, will have a different lighting system, that one hogged too much CPU anyway
