I genuinely, really enjoyed this. I managed to clip through the ground when you throw the first part into the little meat thing on the right of the machine, and apparently if you happen to remove the square or the cylinder from the thing when it's about to suck it in it crashes the game.
I still wanted to complete it though, so I did. I love the vibe and it's really tapping into some cosmic horror deal that's simply unexplained. You've set up a really neat universe and this would be something I'd be interested in seeing a full version of.
I would love to make music for this if you ever make an expansion on this, or if you have any other games planned that are in this style I would be delighted to provide music and sound effects.
