Nice so far.
3 suggestions
1. When selecting the type of drink the, selected box (the highlighted box) needs to be slightly more visible as too which on is selected.
2. This one I couldnt really tell, but for the upgraded coffee machine the needle being slower is nice, but maybe increase the green safe zone. (speed is important)
3. Once you get the den and get help, maybe add a how much you make 'an hour' counter. (something you see when you're in it). Not sure if that is 100% easy to do.
Nothing to really complain about. Great start to a game, hope you get to finish it to completion.
