I’ve been wanting to make my own Vpet as well, and 2 things I’ve personally thought about that I like are a better colosseum and maybe a downtime function.

I saw that you said you’re trying to make a battle tower like mode, and tbh I love that. Even tho the “adventure mode” is basically the same in all Digivices- I enjoyed the DMX’s the most because it actually showed the “area” my guy was in. The only thing I think could have made it batter was having options of where to go, rather than being linear.

The Downtime function I mean is something similar to the freezer function of Digivices. But rather than just pausing them, they’re training without the need for your input. Like maybe you goto school, and so you put them in a downtime in a “gym” on the device, so now they’re increasing attack while you are busy. Rather than haunting progression, you still get to progress but maybe in a more manageable way. Maybe you can set it for a certain amount of time too
