- the text area should auto-scroll so that I can see the latest messages without manually scrolling down
- some responses were written in non-English, no idea what they say
- I got a game over after 14 turns of trying to guess what to type and that felt pretty random: maybe somehow tell the player that they are on a timer
- After several game overs, I looked at the description and walkthrough and saw that my "get plant" was expected to be "take plant": most text adventures allow several different variations of an action so that people do not have to guess the right word for an action (or I should've just read your description first, hehe)
