It took me a moment to figure out how to play the card game, and some things felt like bigger things than planned, but other than that you nailed it! The speed was definitely something. The card game guy made me feel like I was playing Inscryption.
Like builds.games said in a previous comment, there was a bug with the inventory thing but I found that closing and reopening it caused the numbers to update correctly.
I liked the sandboxy nature, one thing I struggled with was not seeing the options button in the lower left corner which is also where you hid the tutorial.
If I had to add one thing it would be an interactive tutorial. Other than that you did great!
I am here because you played Fatten the Beast from that forum post.
