Thanks, the art part is a major problem for us, we will try to learn to make a reactive buttons without modify any art in the future (becuasewe only joined as programmer and game designer duo, one of us got caught up IRL). The recommendation on making the room is more included with the puzzle was spot on, we were confused on how we execute the puzzle 4 would be, many ideas and/or many systematic,and including the room one is slipped off but perhaps it can be made into a new puzzle would be fine as well. Thanks for the idea! The last puzzle.... yea it's just weird, we were like "how can we put grass in the room?" and just before the idea was scrapped, i remember there's a thing called a grass carpet and we go from there XD still perhaps we should more clarify it in the game. Thanks for playing!
