This was such a cool little game! I agree with the comment that assets should be preloaded. For some reason the only item image that ever showed up in my inventory was the nails. I spent a really long time looking for the bucket only to realize that I had it already and could use it on the plant. None of the other items after that appeared in my inventory, but I just trusted they were there and was able to proceed through the rest of the game. I had to look at the source code for help, but I was super impressed by the clarity of the code there too. Nicely done!
