Very cool! The core game mechanics are in place and you just have some refinement to do. I hope you don't mind feedback:
-Movement feels kinda fast. I had to zoom in a little from the default view, but after doing that I end up whipping across the screen pretty fast.
-I was getting random interruptions with thoughts like "This herb could probably be used for ___", but I don't think I had actually picked up an herb when it happened or interacted with any. Actually, while typing this I heard a little "ding" sound and maximized the game to find another notification about a different herb. So this seems like a bug. I'm using W10 for reference.
Keep up the great work!
