Thanks a ton for playing, and the great feedback!
>"like displaying an outline of the shape you’re about to add on hover"
This is a great idea, and would help with a lot with clarity.
>"Win/fail state not very clear. After a playthough I think the goal is to survive for as many turns as possible, and failure is when one of the shape types is extinct."
Yes exactly. I hoped the count of shapes would help make that more clear, but I should give some more warning (like text turns red when you are at 1 shape left). You can also lose by filling up the grid completely, but that doesn't happen often right now.
>"Once I clicked on a rotate button, I couldn’t exit that state."
Apologies, this is 100% an oversight.
Thanks again for the great feedback, it's already given me some great ideas!
