I can’t get it on my Apple Watch in 2022?Maybe I’ll try it again

Doesn’t work with watch

I downloaded the app but it doesn’t show on the watch at all. Nothing works

The app doesn’t work on my watch

I can open the app only on the phone, but it says that you need to open it on the watch, and there is no app on the watch

Geht nicht

Auf dem Handy ist die App installiert, allerdings installiert sie sich nicht auf der Apple Watch und wird auch nicht als mögliche Komplikation angezeigt.

Too hard to keep stats up

This app would be great, if it wasn’t so hard to keep his stats up. There are three stats that you have to keep up: energy, fitness, and fun. You keep them up by telling Mu to do certain actions. Each action takes a certain amount of time and a certain number of coins and restores a certain amount of the stat. To earn coins, you need to send Mu to work. These work actions take a certain amount of time and earn a certain amount of coins.

It’s really nice because it does take attention, but you need to wait for each action to be completed, so you need to check back later, rather than doing everything at once. It makes it less boring because there’s always something more you need to do when you get back, rather than taking care of everything all at once and then having nothing to do for 4 hours. It’s like sims. You have to wait for actions to complete. And it makes it more realistic.

The only problem is that it doesn’t give you a notification when Mu is done with his action. So you have to estimate the time yourself and just check back when you think he might be done. There’s also the issue that Mu’s stats continue to go down even while you’re sleeping, making it impossible to keep his stats up without being alerted when he finishes each task, and even more impossible to get his stats back up after they go down. The time it takes to do each task only does so much as to keep his stats where they are, but when you go to sleep and check back again the next day, all his stats are lower, and you can’t get them back up again, because of the time it takes to do each task. I deleted the app because of this problem.

Can you please add a feature where My goes to sleep for 8 hours during a certain time, or a time of our choice, and doesn’t lose any of his stats? Otherwise, maybe make it so that each activity gives you more points toward each stat, so that the stats not only stay where they are, but also grow, so that when they do fall behind after we wake up from 8 hours of inactivity, we’re able to catch up and bring the stats back to 100. Do this, and I’ll be playing this again.
