Very fun game!
The only issue I have with it is that sometimes it's hard to see a number and due to similar colors you can for example mistake 4 for 1 (happened few times for me).
Oh yeah true. I'm just saying that with default settings, on grass with a bush or sth it's can be hard to see them but I can see now that there is an opacity setting too. Just wanted to give feedback.
Oh and autosave would be also good to have, closed a card and got send back like and hour to the yesterday's save
