If you play both android and pc games, play this on android. No controller support. Windows is a mixed bag.
The latest download I had from earlier this year to play last week was what I thought was a normal exe (DigitalTamers02-V1.0.4), that didn't work. Now the creator switched to an installer. Not that biggest fan but it's whatevs, just install to the folder you want the game to exist in.
For Windows, mouse only, left click only. No way to quit out the game without using your keyboard. Oh yeah, you need a keyboard to quit, as the settings doesn't give that option.
Good game overall though outside of the experience of setting up. It hits those boxes of raising a pet on a mobile device, and being able to jump into different worlds. Here's some unlisted gameplay on Windows if you want to see before diving in
You're correct, I think because when I zoomed in (you can see me doing that at 32:11), the x disappears. I suppose that the X button is only available when zoomed out?
Maybe something to adjust in future updates because once I zoomed in there to see my digimons better I completely forgot I ever zoomed in after a few minutes (I played for another 20ish minutes before switching to a GameJolt Digimon RPG).
