I liked the idea of it, although I am terrible at converting ft to in so I had to keep using another browser tab to calculate how to change my height properly. It was a little confusing how often you needed to hit the buttons as well.
This was fun! I enjoyed playing, and it wasn't too difficult to pick up on how to play. I felt like it was never worth the risk to steal because the odds were so low, so I pretty much stopped using that feature. I'm not sure if anyone ever stole from me.
Even with the instructions it was kind of difficult - I never found the date for instance to know if something was due or not. I would love to see this built out more, though. I think the idea is interesting and if you had the time to add proper onboarding etc. I could see it being really fun.
