Hey there!
I really loved how therapeutic this game feels. The art style and the concept help you relax after a long day. I can see you've spent a lot of time on this. I also appreciate that there is a tutorial. It makes things clearer.
Though - this might be because my computer is low on memory - it is freezing from time to time when I am trying to play. I saw that someone suggested a graphics settings. I think it'd help.
Great job, and good luck!
