This is pretty fun. Most of the levels were easy for me, except for two; The second level for some reason and the first level that had the locked carrot. On the second level, I kept wanting to put a sticker where the sticker inventory was and it frustrated me that I couldn't move the inventory or minimize it temporarily. The first level with the locked carrot took me way longer than I care to admit to figure out, and once I did I felt stupid for not figuring it out earlier.
Overall, really nice job.
