I really like this game! Although, it does get a bit boring but I do understand since its still in development. I'm waiting for the next update! :))
Here are a few recommendations:
FOR UPGRADES
> Better coffee machine = higher carry for coffee
> More time (maybe)
> Waiting time for customers
GLORY DEN
> Maybe also a minigame for that? I'm not sure... But I would really like to see Viola in the same position of the white-haired girl (I forgot her name, sorry!) instead of the bed scene every time
I also saw an earlier comment about the trans/futa and woman-on-woman feature and I also would really love the addition on that.
Overall; this is a very good game! Kudos to you!
