I absolutely adore this game's concept, and I'd love to see a more complete version of it!
Unfortunately, there were a few serious issues I had with it as it is.
As other have said: the mouse sensitivity is way too high.
My second issue is clipping into the floor beneath the front of the slime-milking-chair-apparatus; I'd walk near it, usually trying to place or remove jars from the mixer, and I'd suddenly get moved down a few feet and right at the front of the seating, unable to move at, which happened three times to me and forced me to reboot the game each time.
Lastly, I find it difficult to figure out where to click for environmental interactions a lot of the time, such as placing or removing jars and activating devices (frequently I'd grab the girl instead of the jar she just filled). Some sort of highlight on intractable spots/things, or some overlay text when mousing over something you can interact with, would be GREATLY appreciated.
(Also, I'm not sure how intentional this is, but I wasn't able to buy anything from the shop; maybe it's just not implemented yet, but regardless).
But yeah, I absolutely love what this game is doing. I love how the slime girl works, I love shop and crafting sim type games and this seems like a fantastic iteration of the idea, and I'm really excited to see more.
