A good game that I can see plenty of more potential puzzles, short as it was, I was experimenting on how to solve each puzzle and use a lot of trial and error, so it got my brain working.
while the theme of 'expanding' is present here, it kinda defeats the purpose with the ability to shrink, fits more or 'growing and shrinking' when the theme is more focused on the growing.
aside from that, good job.
