Those are great ideas. Some of them are easy to develop and some are not so. I sometimes think about developing a second version but haven't been able to find the spare time. Your feedback is a treasure. Thank you so much!
a second version would be great, just take some time in the holidays or something and a step at a time you can make it! you also don't have to do all of this in one time, you can do many little updates. Also i'm curious about what game engine you use...
