This game was so sweet! Utilizing the word limit by making a main character a cat, so you communicate in very simple sentences, is such a cute but also wise decision.
The lack of images definitely cuts off the major part of the game, tho. :( What you can do is try uploading your photos to any random image source website to store them online. I used (https://imgbb.com/) for my project. After you grab the URL link and paste it into your project using <img src ="yourimageURL">, your image can be accessed on any device.
Hope this helps, and I get to see more pictures of Sputnik!
