I at first downloaded this for free because I'm stingy, but after playing through the main story, I found myself really enjoying it! The game made me chuckle on parts, and the story was so damn heartwarming. The length of the game, while rather short, was still a pretty reasonable length I think. The puzzles weren't so challenging that they were all impossible, but whenever I would solve a puzzle by myself I would feel quite proud. But with that said, the guide was definitely a good addition because there were still some puzzles that I had no idea how to solve. I ended up deleting the game from my computer and buying it this time because I really don't think it deserves to be downloaded for free.
Now all I have left to do is go through the secret route and see what happens!
Nice job, you made a good game!
