I mean it was pretty cozy and it was actually finished so I didn't have to mentaly skip over unfinished parts.
That said you hooked me at the start with the upgrades changing the café visually. - so I wanted to try and see what all upgrades do.
Shame the later ones (to my knowledge) didn't change the scenery. Though I suppose that would be too much visual clutter. But at least the beer kegs would be lovely.
Also thinking about it now I had the upgrade screen open for the entire duration of the game -> it was nice it didn't obscure the rest of the screen so I didn't have t oreopen it all the time but it was also a little slapped on -> having the upgrade screen be somehow more part of a screen -> even something like a sign hanging from the sky would be very nice.
That said I still think your game felt "finished" enough so I enjoyed my time in it.
