Visuals and the overall game premise feel very cozy.
Unfortunately the game suffers from a big communication problem. I had zero idea what I was doing and could only figure it out through significant trial and error. I know there is a text tutorial but text tutorials are no substitute for either good affordance or a proper interactive tutorial.
The add-in names were also sometimes hard to read and if they were in the left half you had to fill them in without being able to see how much you need at a glance.
There is also no indication that I could see of the presence of snowmen if you're not looking directly at them. This made having to deal with them a chore and very unforgiving, as you could get a game over at any time without any warning. Something like subtle spatial audio cues could fix this.
These are all communication issues that I think could be fixed, which in addition to some keyboard controls and ambient sounds could make this a really nice cozy game.
