Glad my laptop has a touch screen so I could experience this the way it was intended, although it did still feel a little cumbersome since it felt like I had to tap or swipe a little earlier than I normally would, and sometimes it wouldn't register. I was also going to bring up the lack of a level select and the fact it just boots you into a random level, but then I beat a level and it transitioned into another one, so I understand the decision now.
Otherwise, this was pretty fun. The graphics and sound are clean and give sufficient feedback to your actions, and it manages to be challenging while keeping things relatively simple. I'm not sure how it's supposed to tie into the "gather" theme though...
